Interview Preparation Tips
Experience: First round was a written test which had 20 MCQ's in the field of Databases, Theory of computation, Operating systems, Data Structures and Algorithms and one programming question. 7 students (4 B.Tech, 3 M.Tech) got through to the interviews. Most of the interviews were held in the Google Bangalore campus. There were a total of 5 rounds of interviews. All based on Data Structures and Algorithms. Each round had 2 questions for which we were usually supposed to explain the algorithm first and then write the code on a Google doc. It was a really great experience. I got a chance to visit both Google Bangalore and Hyderabad campuses and taste their awesome food.
Total Questions: 20
General Tips: Practice your coding skills. Writing a neat code is very important. Interviewers not just look for a good algorithm but also your coding style (indentation, variable names, simplicity etc.)

Interview Preparation Tips
Experience: I was asked to take the test at 8.30 pm. They fixed this test, a week back. Nobody will call you to remind you to take test. Nor the interviewer will call you. It is your responsibility to check ur mail without fail. On that day I was expecting a call from google from evening till 8.25 pm. None called me. I thought that they would have forgot that. I planned to do go out and have food. But suddenly my ipad gave a alert message and it was from gmail app [thanks for ipad, or else i would not have checked my mail in lap top]. It was from google recruiter. The mail stated that he has shared a doc with me and i must answer the questions in it. a google drive link was given. he mentioned that the test was for 2 hours. I was asked to type answers just below each of these questions.
Duration: 120 minutes
Round: Technical Interview
Experience: Since I had prepared for tech interviews like amazon, I was able to do it good.After a week I got a call from HR and informed that I cleared the first round. Then after two days I was told that i will have a telephonic interview with one of the google developers from adwords team . They scheduled a telephonic interview the next week
Round: Technical Interview
Experience: 1) How will improve the revenue of the cafeteria of the office. Lots of discussions went and i think, i really did that well.
2)[Actual question which i screwed up. Bad Time for me]
Number of users in 2001 for adwords, chrome, gmail, android and picassa are in the ratio of 6:9:14:13:8, and in 2004 we add 3 lakh more users. New ratio is 8:12:13:11:6. Number of picassa users in 2004= 1,44,000. Calculate number of adwords users in 2005.A basic math question that, even a school student can solve. But in that tension i was not able to do it. I took some time and finally gave him a answer. I myself knew that it would be wrong. But interviewer said great lets move on to next question[just to boost up me - good person].My actual job role revolves around developing tools for the the ad review team which will review the ad and reject illlegal ones. So third question was related to that .He told me that as I am from a tech background, I need to explain him technically wat will I do. He also said that he did not need the actual solution. They will just see the way I approach the problem. That an existing problem and they are open to suggestions.3)In google adwords there are about 30 million ads from 42 lanuages . What will I do review the ads and reject ads that do not comply with specific rules .Regarding the criteria under which google bans a ad as illegal – I discussed about different criteria .Out of the criteria’s i told , he asked me to consider only three criteria .
a) Link not working
b) Drug related ads
c) trademarks[trademark used by the companies]I gave lot of approaches like for link not workinga) designing a autobot which will automatically click ads link and check whether it is redirecting to correct page or not . Autobots are used by hackers to get money for the ads they posted . I suggested that by designing similar autobot we can validate the link.b) to check drug related ads -
To detect the language we can first check the geographic location from which the ad is getting posted and can narrow down to some less choices from which we can detect the language
i suggested him that we can create a trie which some specific keywords (like coccaine ) and do pattern matching with that and reject the add it contains any of the works in trie .The interviewer gave me another constraint wat if there comes a ad “coccaine rehabilitation center” we should reject those kind of ads na . thats for a good cause . So i suggested him that i can maintain another set of trie which can contain those set of keywords.Fist check trie1 if drug related keywords exist .
Next check trie 2 if other types of keyword exist.
– if keyword only present in trie1 [reject ad]
– if both tire return true [can reject . but its better that those ad's alone can be subjected to manual evaluation for rejection].I used trie as it can do the pattern matches faster .For trademarks also I discussed using similar datastructures and the interviewer was ok with my answer.
General Tips: I applied for a job in Google jobs page. I know that its very difficult that a resume gets noticed by google.Suddenly one fine day i got a call from Google HR saying that they are interested in my profile and asked me if, i was ready to go with the interview process[Come on! who will say no for Google]. I was surprised.I was asked to take a initial screen test [Online test].

Interview Preparation Tips
Experience: Deloitte selection procedure involves a written test which is
same as CAT format (certainly not that tough). Though I had not joined any test series to prepare for it, but I must strongly recommend that you should actually join a test series (provided by Career Launcher or
TIME). This test series will actually help you to synchronize your mind to the format and moreover it would help to refresh the question solving skills which you used to exercise while preparing for JEE.
Round: Group Discussion
Experience: general topic is given (mostly it is as to how you would go for implementing a new type of technology in a company, and hence you all have to decide the stepwise procedure for the implementation), then whole of the group is called in presentation room where each one is told personally to speak about the same topic as that of GD. This constitutes
second round. Finally, if you clear it, you get to face the interviews.
Tips: From now onwards, start reading newspaper daily. Just give at least one hour reading the editorials from newspaper and make it your habit. Not only for GD's, but for life in general, its very important that you should have a certain view about things happening around you and in the world and newspapers are the best thing which help you form your views and also know about the expert opinions on day to day topics. So, make sure that you read newspaper daily.
Round: Other Interview
Experience: For interview, main thing is that you should be well conversed about everything you have mentioned on your resume. So, before you go for any interview, just make sure that you can speak about for 5 minutes on
every single thing in resume. Deloitte is a company which is open for all the btech students and hence its mainly looking for the students who have a right attitude and are good at their interests.
Tips: have a perfect set of communication skills. I had not done
any special type of preparations for the interview or group discussions but all these skills actually developed during these years. I would advise that in order to gain more confidence at speaking, you should start taking challenges from now on and should actively participate in any sort of debates and GD.

Interview Preparation Tips
Tips: Have a well prepared resume that suits for the role you are applying for.
Round: Technical Interview
Experience: They asked me a lot of questions based on my resume. I had done a lot of projects and courses related to Finance. I infact wanted them to ask me questions related to that as i was very well prepared. I told them about my passion for finance and the director who was from IIM Ahmedabad started asking me questions related to that. That i answered pretty well.
Tips: Be good at what you do. Prepare all your resume points in detail. Theres no excuse to that. Doesnt matter if its related to the profile you are getting interviewed for.
Round: HR Interview
Experience: Except the background and about me I was asked more so of why I was not applying for a finance company and why only Deloitte. I was frank and told them that because of the recession ( euro zone debt crisis at that time ) very few companies came on campus. Hence Deloitte. But also explained them that I liked Deloitte Consulting profile as well because of the kind of work profile it offered.
Tips: Be honest and clear about what you want. They can easily catch you otherwise if you are faking or not.
Do not be hesitant to tell them why you really like them - it could be the work profile / money / etc or a combination of these.
General Tips: Be calm and Cool ? - No. You cant be i think if you are serious about getting placed. [ I feel ]
Prepare smartly ! The more the hardwork, higher the chances of getting your dream job. Many think that it just goes waste but I feel that more than the interview and getting a job you develop a lot of skills under that placement pressure and you should be very positive about it.
Many of the people just chill out completely after placements even if they get a job they dont like.
NEVER GIVE UP ! You spend 70 % of your life at work, hence do not compromise or settle for less. You will regret later on that you did not try enough.
I did get into JP Morgan - Equity Research after Deloitte :) Its a separate story that I left that company as well in 4 months and started www.AmbitionBox.com :P
Skill Tips: Most of them you would know but revise well before the interview so that you dont get stuck anywhere while answering. You should at the bare minimum know the very basics of Finance, Infrastructure planning and Management and Bidding. Also it depends on the coursework you have done. The interviewer might ask you questions related to that.
Skills: Communication, Infrastructure Finance, Financial Modelling, Infrastructure Management, Project Bidding , Valuations, Cost Analysis
College Name: IIT MADRAS
Motivation: The profile was good. But frankly that time since i was more inclined towards finance I wanted Bombay as my location being the financial capital and the office at 30th Floor excited me :) Also there were a lot of investment banks in the new Indiabulls Office building, I just thought I could apply off campus there and get in. In retrospect all this sounds very immature. Net net it was all worth it to help me decide what i really wanted :)
Funny Moments: After being rejected and told over qualified by Credit Suisse and Nomura backing off from placements at IIT Madras because of slot issues I was directly going to sit for UBS Verity.Had prepared the least for this company. Had not changed my resume for the profile it offered. Was not well dressed. ( Not that its VERY important ) Did not prepare anything much. Had given the interview in the most causal way. But against all odds someone had already decided that this was the company i would get placed in - DESTINY ! Felt very strange at that time because had prepared really hard for other companies.
Conclusion - After seeing a lot of my friends getting placed and reading a lot of reviews on AmbitionBox of seniors - 70% of the people get placed in companies they least expect to get into :)
PS: Doesn't mean you stop trying :) Keep trying ! There's immense satisfaction when you get something you truly wanted after a lot of Hard and Smart Work !
All the best ! Most of the advice we give at AmbitionBox and that you probably get elsewhere are just hints to solve the equation and not the solutions themselves. So make your own recipe for success.
Hope this helps :)
