Insider One Senior Software Engineer interview questions

There were 2 interviews. I've been asked about expected salary and got the resposne as It was a bit higher than their payment policy etc. and they say their working hours are flexible.

The technical interview process was poorly managed, with interviewers displaying a condescending attitude and providing inaccurate feedback on my assignment. During the case study, my questions were misunderstood, and I received little support in clarifying the problem scope. Overall, it was an unprofessional and disappointing experience.
