BCG Associate Interview Questions, Process, and Tips

Round: Resume Shortlist
Experience: Your resume can only get you an interview. Beyond that, I guess everyone is on an equal footing. I believe that once shortlisted for a consulting interview, your CGPA and/or extracurricular achievements don’t matter so much that it can make your selection.
Tips: Made a good resume (after dozens of iterations).

Round: Case Study Interview
Experience: I solved in 20 mins, all the while explaining to interviewer my thought process.
My 2nd, 3rd and 4th round of case interviewers did not spend any time on 'chit chat' and went on directly to give me a case.
Tips: I believe what they were looking for was confidence, clarity of thought process, logical deduction at every stage of problem solving and poise, if and when you go wrong and realize your mistake. Case interviews are a simulated work environment; the interviewers will treat your performance as a proxy of how you would do in everyday consulting work. This includes checking for 'fit' or likeability.
There was not much time spent on discussing my resume and/or HR questions, so I should have been selected because I did the case studies well. However, please do not consider this as a reason to not bother about your resume at all. Consult interviewers may pick up any point/word on the resume and you do not want to be in a situation where you can’t explain/talk enough about what is asked. I had spent considerable time preparing for everything on my resume.

General Tips: 1. Made a good resume (after dozens of iterations) and knew it well
2. Prepared for HR questions, rather than just looking up answers online
3. Practiced GDs, did mock interviews as frequently as possible
4. Revised quant
5. Current affairs. And by that, I don’t mean just knowing what is going on, but having an opinion about all sorts of issues
6. Didn’t spend too much time after one particular sector/company. And got to know every company/sector's style of interviewing from seniors who are placed there. Attended all placement talks to understand what each company is looking for.
Skill Tips: It is necessary to understand the consulting interview process well, as there are specific traits which firms are looking for in future consultants and which they will definitely test through case interviews. I did so by practicing cases with friends and seniors working in consulting
Skills: case studies

Round: Case Study Interview
Experience: CASE 1:
No numbers were expected, neither knowledge of broadband technology. The key here was increase in the number of uses along with the users. None of the established frameworks really helped. The interviewer was very helpful and gave me cues when I was not making progress.

CASE 2:
Again no numbers no data was expected. On asked about the missed out aspects, the interviewer discussed the key aspects with me and also told me where I had gone wrong.
Tips: 1.When they ask questions about academic projects try to pick something with practical applications.

Round: Case Study Interview
Experience: 1. The interviewer told me exactly what he wanted.
2. It was a two way discussion and a very comfortable conversation3.He told me the four departments he wanted me to look at.
4. I was to check for 'synergies' or potential benefits of the acquisition of these departments.
Tips: 1.Sleep well.
2.Wear comfortable footwear.
3.Don't starve yourself.
4.Sit down a minute between interviews and take deep breaths.

General Tips: 1.Attend PPTs of all companies you are interested in.
2.Don't try and squeeze too much in your resume.
3.Case studies are must for consultancies so be careful in that.
4.Don't prepare answers to the last word, but think about some common questions.

Round: CV Submission
Experience: This is an elimination phase, so it's important that your CV puts you in a good light. BCG would most likely conduct a CV building workshop. If they don't, McKinsey would. 
Tips: Keep in touch with seniors and get their advice and opinions too. Make sure you're happy with your final CV, and that it has been okay-ed by enough people before you ship it out.Don't make your CV on the last day. Put in sufficient effort - it will pay off.

Round: case workshop
Experience: BCG conducts a case workshop a couple of weeks before the interview process starts.Since the interview is entirely case based, make sure you pay attention in the case workshop. 
Tips: Also, it is advisable to form groups of 3-6 members with whom to practice business cases. I would suggest that you start with your case preparation in advance of the workshop, so you have things in perspective by then. Case books to practice cases from would most likely be circulated in advance. It also helps to make up your own cases, and have cases administered to you by people in Consulting.Do ask good questions in the case workshop. Although it's non-evaluative, it pays to make a good impression straight off the cuff.

Round: Case Study Interview
Experience: Four interviews (2 rounds with 2 interviews each). Out of the 21 shortlisted candidates, 12 made it to round 2. Out of the four interviews, one was with a Senior Partner, two with Team Leads, and one with a Principal.My first case was about optimizing the transportation logistics of a cement manufacturer. The second case was about figuring out the issue with the business model of a hotel franchise experiencing falling revenues. The third case was about figuring out the reason for falling revenues of a retail outlet in Sri Lanka. The fourth case was about troubleshooting a new house-loan sales strategy, which was not performing up to expectation.Same set of skills as mentioned above. Make sure you're clear in what you say. 
Tips: There will be some minimal HR, which you must prepare for. The discussion will be a lot more informal than you would expect, but make sure your answers are crisp, sharp and to the point. Feel free to be exploratory and creative, making sure you're telling the interviewer exactly what you're thinking. They'll be at least as smart as you are (trust me on this), and it won't take much effort on your part to explain what you're thinking. Work with him/her. This is important. Don't be too slow or too fast. Develop a style based on your practice sessions, and play your strengths.
