Emotionally fragile staff. Inexperienced HR (sorry "Culture") team. Leadership team subjugated to the CEO's decision making. "Feedback" culture not actually a thing,
What happens when you hire a load of slightly above average people from a very restricted talent pool (of those people willing to commute to Knutsford every day), tell them they are all amazing, and pay them WAY above average?
A group of people terrified of any change, suspicious of competent new joiners and willing to use emotional manipulation to deflect any criticism about their behaviour.
Yes, Portswigger have cornered the market as a result of their feature rich bloatware, but their dysfunctional culture will not sustain them now that challengers are coming for their crown. The cash cow will soon stop dishing out milk.
Currently the leadership team is the gang of eunuchs to the CEO's crown. The weekly all hands is the equivalent of the court jester's roundup, and no guys, your in-humour isn't that funny at all.
The culture of feedback isn't actually a thing at all. What it means is they have a feedback tool, but you can't use it for everyone and some people won't receive feedback either through their diva status or the likelihood they'll throw a tantrum.
If you prefer to operate in an environment based on facts and clam logical decision making, Portswigger isn't for you. If you thrive on emotional manipulation and drama, then you'll thrive there.
