Where to even start... there is no meritocracy to speak of. If you are a French speaker or your manager likes you, limited rules apply to you.
Diversity is dropping in some campuses like Singapore but that's not the school's fault, it is government policy.
HR has zero relevant experience in real world settings - Ever since they introduced a shocking poorly executed compa-ratio policy when discussing remuneration in 2024, most long serving staff that have stuck with the school through COVID and all the difficult times get ZERO increment due to salaries being forced into a band, leading staff retention to drop to an all-time low.
If you are a new joiner and negotiate a good package to join, bear in mind the compa-ratio policy means you will not get a pay raise for at least 3-5 years or until you quit.
All the good people from the past 10 years have quit or are in the process of finding a new job. INSEAD's work culture has gone down the toilet bowl since Francisco Veloso took over from Ilian Mihov.
People who get promoted now are not the performing ones, but rather the ones who are good at carrying balls.
If you want to keep your job, make sure you do not whistleblow on any wrongdoing even if it happens in front of you, especially if it is done by top management. We had a popular ex-colleague (brit guy) in talent acquisition who can attest to this.
There are also some departments in degree programmes who are haemorrhaging long-serving staff faster than ice cream melts in Singapore due to the wonderful "leadership" on display.
Current INSEAD leadership probably got confused and think that they are working at INEOS and not INSEAD, as they are sinking the school's work culture faster than Jim Ratcliffe is destroying Manchester United.
