Advanced Energy interview questions

I applied online through company website and got a call from Company HR within a week of my application. There was one onsite and one virtual screening interview followed by technical interview with the panel of senior engineers. The interviewers were nice and respectful. They wants to gauge the technical depth of the candidate. After every interview I would follow up with the HR and they would guide me on the next steps. The entire process is pretty straight forward and took 3-4weeks.

Quite challenging as 4 people interview me at one time and took almost 1.5 hour. Good and positive ways of interview session,they answering all the questions that i ask. The way they interview more to wanting to know depth of our knowledge.
