Hi Anonymous,

My perspective on that:

1. Short-term schedule: without details difficult to say - but in principle nothing that unusual; if it would not work for you should be possible to re-schedule
2. Definitely unprofessional - but it's a single person's view and behaviour (and possible it was even a test of your reaction), not sure how much it can be generalized
3. While you usual get feedback from MBB, oftenly is not detailed and not actionable ... if nobody gave you feedback proactively, did you ask for it and did they decline? Even if so, it's legitimate - they don't have an obligation to give feedback, and it's still you who wanted the job in principle, so you need to adapt to their rules
4. Recruiting processes were slowing down in general - sometimes looks even on purpose - could be true also in your case. But be assured that one single candidate is not the top 1 priority of partners - even if you might be inclined to see that differently.

Hope this helps - if so, please give it a thumbs-up with the green upvote button below!
