Keyloop (UK) interview questions

The interviewers were professional and the conversations themselves were positive. But you feel huge pressure and harshness already, what's a bad sign. However, the overall process lacked transparency and timely communication. After multiple interview rounds and significant time investment, feedback was delayed or unclear. Candidates would benefit from more consistent updates and better expectation management throughout the hiring process. Proposal was given. But with no proper reason rejected with no further feedback although requested. All in all, if you behave like this in the interview process already, what kind of mess/pressure/lack of transparency is in the company then even?
