first round with hiring manager . no introduction. he went right into technical questions . asked me 3 technical questions . he looked rushed and tired . next i went for onsite . 6 rounds . 1 staff member. asked me standard system Verilog questions . nice to interact with. rest 5 were all senior principal engineers . most looked very tired and rushed . one was mad and disappointed as i could not answer one of his questions . It felt like they are contractors for other companies . HR should train them regarding how to behave in an interviews. questions - lots of uvm , system verilog questions
