HCLTech Embedded Developer interview questions

I attended the interview virtually and Overall It was a good experience and they ask about general questions like final year project related questions, self Introduction.I failed to negotiate the salary.I am not accepting the offer

I applied off campus. Applied in June Test was in aug and I got a mail in Sept telling to send the resume and adhaar card copy. After it was sent within the 2 dats I had my interview. They hadn't mentioned for which role the interview was taken . So I assumed it to be for a GET role and prepared accordingly. It was during the interview I got to know that it was for my core role...WAS SHOCKED...The interviewer asked question about projects(tough ones) and literally about topics outside my resume. Though I didn't know all of them I managed attempting and stayed cool and confident throughout the interview a reason that I consider what made him select me. Again in 2 days I was schedules for the HR round that lasted for less than 5 min(very easy) After 2 days I got a confirmation mail that I'm selected Guys as a fresher just try to appear cool and confident in the interview and have good communication skills. This is what I would suggest
