Round: HR Interview
Experience: 1. At First, I missed the Credit Suisse GD since I hadn’t brought along a portfolio manager (one who handles your interview schedule and attends to the ever-ringing mobile phone).
2. I proceeded to Credit Suisse, and requested their HR contact to give me a chance since I could not turn up for the GDs.
3. It was here that I handed over my mobile phone to my friend Apratim Tiwari, who was managing the Credit Suisse procedures, and requested him to pursue the HR guy to schedule an interview, and also handle my phone when I was interviewing and he had successfully managed to get me an interview with Credit Suisse.
4. The interview went well. They were apparently quite impressed.
5. Two more rounds of interviews, and the HR guy made me an offer.
6. But, since Deutsche Bank was my dream company, I was also interviewing with them and got selected.
Tips: You would need to focus on three broad areas for a comprehensive preparation:
(a) HR questions: This is the most important part for any interview. In companies like DB, your communication skills coupled with your preparation of such questions account for more than 70% of a candidate’s selection. Answering questions about your career goals, interests, and your career thus far should become second nature by the end of November. You must also know the firms and job profiles inside out. I worked on this specific area, and by the end of the placement session, I had gained a reputation among my wingies for my expertise at answering HR questions.
(b) Puzzles: Since this is a non-core sector, puzzles are the only way to objectively test the ability of candidates with diverse backgrounds. Look up braingle.com and techinterview.org. These two should suffice. Also, whenever you come across a puzzle that you’ve already encountered, pretend as if you’re going through it for the first time. Don’t rush through. This is your opportunity to impress them. Do not squander it away!
(c) Finance and economic affairs: If you have a comprehensive knowledge of the financial markets, national economy, and international affairs, in addition to the above two, it is highly improbable that you won’t be selected. For brushing up these, read the Economist (print or online), and read through the opinion pages of Economic Times or the Business Standard for 2-3 months leading to the Placement season. You must also regularly read a newspaper like the Hindu or Indian Express to keep yourself abreast of the latest events which frequently become a focal point of group discussions (for Credit Suisse). You CANNOT afford to walk into the interview ignorant of terms like European debt crisis, global financial crisis, fiscal cliff, QE, and basic finance like options, hedging etc. Wikipedia, Investopedia and J.C.Hull (first few chapters) are great sources to pick up these.

General Tips: 1. If you are a B.Tech. student, do not be under the wrong impression that you can target all sectors- core as well as non-core. It is really difficult to prepare comprehensively for all companies, especially if you are in the B.Tech. program owing to time constraints.
2. The Dual degree students have an edge over you for precisely two reasons. Firstly, they get more time to prepare for the placements, and have learnt vicariously from their B.Tech. batchmates' experiences. Secondly, they tend to have higher retention rates (good for the companies).
3. Work on your English communication skills which are crucial for performing well in interviews and GDs.
Let neither of these become an obstacle by leaving no stone unturned in the course of your preparations.
4. You can’t appear for more than 4 companies in the first slot. It is not realistic. Hence, decide beforehand. I knew I hadn’t prepared enough for consulting or core, hence I opted out of ITC and Opera.
5. If you are shortlisted in multiple companies, ask a reliable friend to accompany you to the interviews, and handle your mobile phone (“managing one’s portfolio”). You’ll thank me someday for this advice.
6. I was happy that I prepared as much as I did, neglecting my college academics in the process. It is a decision I am proud of.
7. My Morgan Stanley internship distinguished me from scores of other candidates. I had never truly appreciated its importance till then. That also goes to show how important it is to get a good internship.
Skill Tips: 1. I scored a 100 percentile in CAT and the preparation made a huge impact on preparing for any of the interviews.
2. I also interned at Morgan Stanley which was further a plus for me.
3. I had received Honda YES Award, University of Tokyo-IIT Scholarship and my academic background was quite good.

Round: Test
Experience: The first round, quite naturally, was the aptitude round. We had to answer questions that were designed to test our quantitative and technical abilities. But this was only the first part. The second part involved finding computational solutions to simulated situations. These questions needed to be solved in a programming language we were asked to choose earlier, during the aforementioned first part. I chose to do it in Java as that is one language I am really thorough with. I understand that C/C++ are more important and versatile, but what matters here is your inherent understanding of the concepts involved

Round: Group Activity
Experience: We had to build model buildings, using LEGO blocks. Other than the fact that I love building things from other smaller things, the supplied material took me back to my childhood days. We were divided into four groups. Two in each room, and each group consisted of 8-10 candidates. We were given a time limit within which we had to design and construct a building. As a surprise, after half time, they asked the two groups in each room to merge their projects. This probably was to see if the candidates were pro-active team players, and could handle unexpected situations like professionals.

Round: Technical Interview
Experience: There was another technical interview after the group activity. I was interviewed by two of their officers, who again asked questions similar to those from the first technical round.  It went quite well, since I was quite confident about the way I was solving the problems they gave me. Thinking out loud is key, as that lets them in your problem-solving abilities. That way, they let you know if you are headed in the right direction. My interviewers were quite pleasant, as they liked discussing possible scenarios to the problems they gave me.

Round: HR Interview
Experience: there was an HR round, where the woman interviewed me about my projects. She needed to know if I had the guts to finish whatever it is that I started. So she asked more on the lines on my role in the projects I had undertaken in the previous years. She also asked me about my working experience from before. That too went well. It was pretty much a standard HR interview – projects, hobbies, traits, etc.

Round: fitness roound
Experience: There was another round in the end, which was to test the candidate’s professional fitness – if they indeed are the right people for the job. I found it to be a blend of technical and HR interviews, more on the lines of HR though. All in all, it was a brilliant experience

General Tips: To my juniors, study hard, be sincere, be yourself, be smart (preferably in that order, but you are free to improvise!)

Round: Resume Shortlist
Experience: They didn't had any aptitude test, only resume based short-listing.

Round: Group Discussion
Experience: There were 10-15 students. There was 3 mins thinking time and 10 minutes discussion time. After the discussion each student was asked to conclude the GD and express his/her viewpoint.
Tips: 1. Jot down your point during the three minutes. 
2. During the GD make sure that you express your opinion coherently. 
3. Also make short notes during the GD which will be helpful in concluding it. 
4. While concluding the GD, ensure that you cover all the points discussed during the GD (notes will be helpful here) and in the end express your own stand.
Duration: 10-15 minutes

Round: HR Interview
Experience: It was a HR + Puzzle round. Panel was of Some junior management and the duration was of 30-40 minutes. By the end of this round, they were quite impressed and sent me for the second interview immediately.

Round: Technical Interview
Experience: This round was based on Current Affairs and Finance and lasted for 20 minutes. And, I asked them a few questions about CS and job cutting etc. After this interview they had mentioned that they were quite positive on me and that I had to just interview with one more senior manager. This really boosted my confidence.

Round: Other Interview
Experience: It was also based on finance and current affairs. Panel consisted of the Senior most employee who had come for recruitment. After this round I was informally offered the job.

General Tips: 1. Even when you are unable to answer questions, don’t get bogged down or disheartened remain calm. DB quite often takes stress interview. Just keep your cool and smile while answering questions. 
2. If you do not know any answer, there is no harm is admitting that.
3. Be confident. Know your resume inside out. 
4. Practice a few HR interviews before the actual one. 
5. Also, communication skills in English are very important.

Round: Resume Shortlist
Experience: My strong resume aided in getting shortlisted for Credit Suisse.

Round: Group Discussion
Experience: The GD went well as I did not haste into my chance and was calm throughout.

Round: Other Interview
Experience: The interview was with an alumni who told me that my GD performance was good, and asked me a puzzle. It was followed by some questions on my resume, mainly my internship.
Another puzzle followed, which I took some time to solve. I was able to solve the next one instantly,
Then I was asked to sell a crumbled piece of paper innovatively.

Round: Other Interview
Experience: This round was with a senior member in the company who asked about my resume, stay in campus, post of election officer and some tricky questions, which I answered well. A question on probability was asked. A few more puzzles followed, along with some questions on finance. He also mentioned that he did not expect me to answer these as I had no background in finance. But i was able to answer them.
I was then asked to leave and HR was called inside. I also had an interview with Diamond. The HR came to me and told me that they were interested in and asked me to stall my interview with diamond for a while.

Round: HR Interview
Experience: It was with VP and continued for 45 minutes with no puzzles, finances or cases. It was more of a discussion on all fields ranging from campus life to UP politics to Sachin's retirement, etc.
I was asked about my internship experience and the reason i wanted to join their company .

Round: HR Interview
Experience: It was with the Director, who said that he had a sore throat and hence would not say much. he said that they wanted to hire me and that I do not interview with any other firm. I was more than glad! I was the first person to bag an offer in the placement season.

College Name: IIT KANPUR

Round: Test
Experience: There was negative marking for these questions (+4 & -1) and the number of questions in the second section were more (10 and 20 respectively, I think).The second part of the test was a Coding Round, online. We were given 3 problem statements to be solved in 45 minutes and the programming languages allowed were C, C++ and Java. However you are required to use the same language for Part 1 (Technical Skills) and Part 2 (Coding Round). So make sure you know any one language in its entirety. I hadn’t touched anything apart from C. The questions were essentially based on data structures.
Tips: Word of caution: Be wise in designing your strategy to solve questions, there always IS a sectional cut off and the competition is cutthroat.

Round: Technical Interview
Experience: -1 was pretty much basic, probably just for them to find out whether you know everything that you claim to know. I was asked questions on the basics of C, Data structure implementation, DBMS AND OS. Sounds daunting, but it really wasn't. My panellists were really cool about giving me all the time in the world to think about my answers, they'd even roll their chairs to the corner of the room and chit chat when I'd ask them to stop looking at me. Not a recommended course of action for you guys, because you might get really badass panellists who might want to take a stress interview and using this would probably get you a ticket to take you directly out of the building. But the point is that you don't need to panic when you're asked a question that you don't understand AT ALL. It is probably just a coating of shiny silver on a very basic problem. ALWAYS remember to restate the question as you understood it to make sure that you're on the right track. If you're right you get a bonus for being able to analyse well. If you're not, they will make you understand and you won't spend 15 minutes of your interview time solving a misinterpreted question.

Round: Group Activity
Experience: This is subject to change every year, but for ours we had the one with the Lego toys

Round: Technical Interview
Experience: This round was perhaps the most difficult of all, with gruelling technical questions that I couldn't make head or tail out of. But they were satisfied with a broad outlook to the number of solutions and the different ways to approach the problem. They asked me a little about how my day had been till then and for improvisations on the answers to the questions I was asked in the previous rounds. I was also asked a question about synchronization that I answered with my knowledge of embedded systems. They were really interested in how I applied unrelated knowledge to solve a problem that I would otherwise not be able to answer. This was the end of TECH-2 which made me believe that I had screwed up entirely and that I was out for sure.

Round: PRO FIT ROUND
Experience: I went in to my ProFit round with an "I-should-really-have the-best-time-with-this-thing-since-it-is-all-down-the-drain-anyway" attitude, but really, I think that is just what you're expected to do anyway. :) This ended up being the coolest round of all and I had the time of my life for those 30 minutes. My interviewer asked me ALL the general questions you expect in an HR, and I answered them all very, very truthfully and with really long explanations :P The guy was a veeeeery keen listener and caught on to each and every one of my indications. He let me talk about practically everything, from my very hippie-like outlook of life to the most silly bets I have placed, ever. And the best part was that he was always interested, poker-face like, but always waiting patiently for more exemplifications. Don't bother trying to make up achievements you haven't really made, because they don't care about how accomplished you are, more like how zestful you are, and it probably shows when you're talking about things that you love. Long story short, talk your heart out, they hardly speak in all of those 30 minutes. Let them know that you really ARE passionate about the things that you do.

Round: HR Interview
Experience: The next round that I was immediately ushered into was my HR. Now, I probably felt what I did because I had talked a LOT in my previous round, but I really thought this round was predominantly precursory. My interviewer was one of the big shots of the day, but he hardly asked me any questions that could qualify as HR. This person was the only one from all of my interviews who was even remotely rigid, but that too only marginally. He was ultra-friendly again by the end of the interview. This might vary case by case, but he only asked me things like my comfort with relocation and what I aimed to achieve in the next 5 years. At the end of the interview, he kid around a little and escorted me to the waiting room.
