Initially, I got a call from HR to know if I am interested in the job opportunity. After that all my communications were with the manager whose team had openings. So, we (me & the manager) set up a preferred time for initial phone screening. In the first round of phone interview, our conversation started with introductions from both sides and making sure we both are interested in proceeding further. Then started technical round with some actual interview questions.
I had 5+ years of experience in Java and was asked questions about design patterns. They were not direct questions but real life problems and how to solve them using design pattern. Then there were also few questions on high level java. I was able to answer most of them. So, the manager concluded the phone call with a note saying he will get back about the exact date when I can come to the company for in-person 1:1 interview.
Then was the in-person interview. I went to the company location on my own and the interview started from around 10Am and lasted till 5:00PM. Was interviewed by 5 people one after the other. Questions were mostly on high level design of enterprise systems and applications.
At the end of it, had a short meeting with the manager again and it was clear that he was interested. But he informed that the formal communications will follow. Got email few days later with details.
