The overall process is generally ok, the interview is quite enjoyable. The interviewers are all very professional and trying to offer you some help. I did a standard bain case interview there and the questions are fairly standard. Although the cases themselves are solvable but definitely requires a lot of practice & self training. I'm not from a business background so I didn't prepare very well. One of the major critics I have is Bain's online screening test system is quite poor (in fact the worst I have seen). The system itself paralyzed for several hours on the day I tried to complete the test. And even after they brought it back online it still crashed after I submitted my answers. The online test questions are very challenging, they take both your accuracy and speed into account.
