HCLTech Senior Software Developer interview questions

I have attended for position firmware engineer. Total 3 rounds happened. 1 st rnd: asked bitwise question like count set bit in a number and related questions 2 nd rnd: asked about string reverse and palindrome. 3rd rnd: asked about interrupts and project related questions.

The interview was quite straight forward and was oriented mainly towards the position they are hiring. If a technology is not being used they do not ask questions about that sinvmce they also know that we are not going to require these technology skills. Only 2 rounds of interview and the 3rd round is the HR round
