Preguntas de entrevista para el cargo de Principal Software Engineer en Calix

The HR called me in Oct 2021 and started the interview process with great enthusiasm saying they are starting new in Bangalore. But it has been more than 2.5 months since the process started, 4 rounds done and there is no closure in sight - No progress to next round, no rejection notification, no feed back, no answer ! My application status in their job portal still shows "Under Consideration" The interview discussions were mostly pleasant and nice except for one video round in which one hiring manager (director) raised unnecessary cynical doubts on the credibility of the Machine learning course which I had completed in a reputed Indian institution..I just wonder he should have rather googled about the institute himself before calling me for interviews.. After the 4th round, I have waited for two months without any further update.. I had repeatedly requested the HR for prompt update, but they all appear to have fallen on deaf ears.. Finally he pointed fingers to the management and said he has not been updated of any decision. I then emailed the probable hiring managers, and one of them responded that he would revert to me shortly. But not sure what is "shortly" in their dictionary. It has been 40 days since..no answer yet.. No respect shown for the efforts and time a candidate has to put for totally 3 hours of interviews.. I end up feeling like perhaps a lab rat being used for their hiring experiments in India..( In fact, one director's comment was "We are only exploring available skills now..") I strongly doubt this company's management suffer from doubts, indecisiveness, lack of clarity on what they really want in a job role, and more certainly lack of a courtesy and culture of respecting people..

Had a phone screen and then was invited for an on-site at Petaluma, CA. I was interviewed by 7 Senior leaders/Execs. Interview questions were in-line with the job description/responsibilities. I did get a job offer within 3 - 4 days.
