Interview process involved 6-7 rounds starting with screening round with HR, couple of rounds with Directors (mostly on background/experience), followed by a case round, interview with an org. psychologist and online assessments.
Pros: Interviews were generally well structured and professional as one would expect from any top consulting firm; all interviewers provided a realistic outlook on the role and culture at Alix; most interviews except for the case round (for obvious reasons) were conversational
Cons: The interview process is lengthy and not for everyone, especially experienced hires; a significant portion of their mandatory online assessments are identical to MBA entrance exams and feel like an overkill (to some extent silly) for the position in question; was given very generic reasons on why an offer wasn't extended (e.g., "sorry!...there were stronger candidates in the pipeline") after investing 2 months in the process; felt like there was lack of transparency - most top firms will not drag you so much/far before a "yes/no" decision
Don't go by their role titles. Even partner levels are expected to roll up their sleeves and build solutions ground up which is something unique and good about their culture.
My recommendation: It is a good firm but they are extremely picky about who they hire. Don't go in with high expectations, do your best and make sure you're not being someone else that you aren't. Not being offered a position here doesn't mean you're not a good consultant!
