I interviewed at BCG and Bain a while back for US generalist positions as a post-grad experienced hire (<2 years of work experience).
With BCG, the screener went awry (recruiter was 15 minutes late and we chatted for 5 minutes before he had to run off) and then got the standard reject email a few days later. No mention of how long I'd be barred from reapplying.
With Bain, had first round interviews that fell short because I wasn't faithful enough to my framework, though the interviewers told me that I handled all other areas very well. I responded to the follow-up emails from my interviewers asking for advice/areas of improvement but neither responded. No further emails and no mention of how long I'd be barred from reapplying.
Is a 1-year wait appropriate? Or 18 months/longer? Is the fact that the firms didn't say anything to me after the interviews indicative of something or is that in the normal range of behavior?
