SLK Group Test Analyst interview questions

Please do not waste time with this company. I completed 3 rounds of interview (2 technical, 1 HR) and the way they behaved seemed like I was selected and I got happy. Suddenly I got a call saying I’ll have to do a client interview before my position is finalized but there was no meeting invite or anything for that. Not only for that, even for the earlier rounds, they never sent me a mail saying that I have cleared the round, so there was no trace of me ever clearing any round of interview with them. And the HR here are unprofessional, unethical, and never responded to any of my queries properly, but lied to me, saying things like “you are shortlisted, the interview panel likes you, but you’ll have to wait till we contact you back”. But they never contacted me and finally, after a month and a half from the day I completed my HR round, I got to know that they already recruited someone else for the position I interviewed for, from the person who did the technical interview for me. It’s all just an eye wash and a waste of time.
