Interview with project manager asked about my course and projects , my experience . Nothing related to the resume . just about my masters degree . but when I follow up the HR is not replying to my mails . Keep your introduction short and on point .

I had a virtual meeting with the recruiter. That moved forward to an interview with the project manager. After that I was able to visit the job site to see if I would enjoy the type of work. This also allowed me to ask more questions while looking at the work that was being done.
