Preguntas de entrevista para Beyond Evolution Tech Solutions

Didnt know why they call us for the interview...got selected in all rounds...HR called me asking saying congrats and asking for my payslip and previous company's offer letter so that they can proceed further.I responded them with all the details same day.And then waiting for more than two months for thier job letter...when i called them or mail them..they replied...we are restructuring the team..will provide the job letter soon...i cancelled my other interviews because of this...also wasted my 2 days for interview...
