As others have said, the company suffers from an incredibly toxic culture. In my first weeks, I was warned about not getting on the wrong side of certain individuals as they had the capacity to ruin your career. I was shocked to witness this actually happen to a number of people, who left feeling broken by Insights. There is a culture of fear, caused by leaders who are unqualified for the roles they are in. Insecurity seems to be at the root of this problem, resulting in passive-aggressive behaviour. If you have been brought into Insights based on your experience and skills, you may feel as though they are constantly challenged and belittled. It can be quite frustrating and exhausting.
I didn’t feel safe working at Insights. I would only recommend it if you are exceptionally good at office politics and are willing to massage many egos to do well. It is possible, but you will need to turn a blind eye to a lot of bad behaviour and stay focussed on your own career.
