BlueStacks SMTS - Senior Member of Technical Staff interview questions

One of the worst company i have ever met. I gave 3 technical rounds and all rounds got cleared and after that I got offer letter. After 2 weeks i got HR(siddhant) call that we are not able to onboard you as there are some restructuring is happening but i can try for u in my management and after 2 days he called me that management is ready and moving u to another project but when the joining is remaining for just less than 15 days again i got call from HR(Siddhant) we are sorry we can't onboard u. Please search for another company.

there was around 4 round of interview, 2 technical , 1 Managerial and 1 HR, you have to clear each round to reach end get shortlisted. In online interview have to keep camera on.
