Speaking with friends who graduated from the program in March.
There is trouble brewing at UCB MFE. 2019 placement is way down this year - currently at 65% one month after graduation!
I agree with the sentiment that a larger cohort size means likely lower placement rates, and that it is in general a bad sign, if all other things remain equal. I'm not discrediting the possibility that placement rates for 2019 may be lower than previous years.
What I am saying is that you destroy your own credibility when you write
and then clarify it's just an extrapolation based on a very small, not necessarily representative sample size.
