TATA ELXSI Senior Development Engineer interview questions

They took all round including 3 tech rounds + HR round on same day, and taken all details and pay slips as they release the offer, after 2-3 days, scheduled one more technical round from manager, and they went away, looks like they are not able afford the package or they simply wanted to show are they in the market, my sincere suggestion is if they have any constraint, please tell before shortlisting or at least before asking to share our confidential data, it is just waste of time for both of us, when you people suddenly went away with no answer, i had very good image about this company before i attend, just they play with job seekers time and their life in this way, please stop if your really not interested with any profile and if your not able to afford
