Pros

Truly embarrassing, if you can't laugh at yourself and the company then you'll cry. The pros are only that leaving a horrendously toxic job is apparently better than a year of therapy for the soul.

Cons

The cons are immeasurable. Regardless of the actual job itself, being surrounded by the type people that bear more behavioural resemblance to epstei files nominees rather than senior figures, or are just complete walking icks, is only really conducive to a highly negative experience to be honest.
