I was contacted by a recruiter about this opportunity. After a week, I received the schedule for the phone interview.

The interview was with the hiring manager. The questions were related to my current and previous projects, which I explained in detail.

Then, there were a few questions about basic Java concepts (OOPS concepts).

After that, a few questions about performance and memory leaks.

The interviewer was very nice and helpful throughout the interview. He was very happy by the end of the interview and invited me for the onsite interview.

The onsite interview was a Java coding test, and it was in San Francisco.

After a few days of the onsite coding test, I heard from the recruiter that they are not moving forward with my application to the next stage. Overall, a very positive experience and I learned a lot.
