Its easy ,concentrate on basics, better to do advance courses as they will be helpful in your job, they were asking to explain the working principles, and the projects mentioned in my resume

There were two stages in the interview process. The first was a telephonic interview with the HR manager, followed by an online interview with the hiring manager. The hiring manager mainly asked about my motivations and previous work experience. He mentioned that there would be another onsite interview; however, that round did not take place. I have not yet been informed of the result or received any feedback.
