This company is totally clueless. This was the second interview I gave with them. Total 3 rounds in Hyderabad.

1st round went for 1 hour. The interviewer was not having my resume and had no idea of my recent project skills. He started asking me scenario-based questions on technologies unrelated to my recent projects. I worked on them, but long back, so I handled all his questions. Some of the questions, I was totally confused about what he wanted to get out of me or which concepts he wanted me to explain; it was simply going in all wrong directions. He asked me a programming question related to DP and then gave a SQL query, during which he went out and called the 2nd interviewer for the next round, someone senior to him.

2nd Round: I took permission for just an hour from the office, so I had to go back. The 2nd interviewer seemed like he knew about my background, and we talked for 2 minutes. He helped me go out of the premises. During that, he asked me at what level I left my previous organization and my current package.

An interview was scheduled again for the next week. I went for the interview. This time there was no one to receive me. I tried calling the HR number; it was connecting to some wrong office. I tried 3-4 times. Then I dropped a mail to HR that I had been waiting for 15 minutes. Then she said someone would come in 5 minutes. But during that time frame, I called the person who took my first round and explained. He said, "Please wait 5 minutes, someone will come." He was not sure who should be taking the next round.

At last, someone showed up, and the interview started. The guy asked me about my skills and some background. This time I had my resume copy with me, so I handed it over to him. He asked me to self-rate in jQuery, Java, Agile, Spring, Hibernate, AngularJS, and some other skills.

This round went for 1 hour 30 minutes. He started with some concepts around multi-threading and synchronization. Then asked me about Singleton, which I wrote. Then he asked me about making it thread-safe, which I told him, detailing 3 types of approaches: a) Double-check locking, b) volatile keyword, c) Lazy initialization. Then discussed locking. Somehow, he kept asking silly things on synchronization concepts and wasted a lot of time, which he could have used on some other topics. Then he asked me about SQL, Spring, Hibernate about connecting to two DBs, and many other things. This was a long interview. In the end, he asked me about the package I am getting currently.

Then he asked, "I will go to the manager and give the feedback." I told him I told the person who scheduled the interview that I can give 1 - 1 hr 30 mins max, as it was a weekday and this team was not available on the weekend or morning hours. He said, "Just wait for 5 minutes."

I kept waiting for almost 20-25 minutes, looking at the walls, blank projector, and markers. There was no water in the interview room.

He came after 25 minutes and gave an excuse: he was on some call. He just ran through some concepts and was more into the UI side. I answered 90% of his questions. It was around 15 minutes of interview.

Then I asked him whether there would be any further process. He said he was not sure if more people wanted to talk to me. Then he helped me go out of the premises, and while walking, asked about my notice period and a few other basic stuff.

It was a Thursday. I was expecting a response from the HR. There was no response to my email. Then I kept waiting till Monday evening. Then I called the HR; she said she dropped a mail to the manager but got no response. She said she would find out if I was on hold. So after that, I kept following up for 3 days in a row, and she said the same thing. The interview for me went really good, so I was curious.

Then she told me that the Manager told her that he was taking interviews for 3 more guys, which would be over by the next Monday. I chased the HR next week again, and she said that position had been filled by some other guy.

The HR was totally clueless; I had to chase for a proper closure. If I would not have followed, I would have never got an update from their side.

HR in such companies abuse their power and reputation. And all the interviewers asked me about the package, which is kind of strange, and generally, I prefer talking about that either before the interview or in the final HR round.

Regarding synchronization, if each object has its own Java stack where it creates its variables and other stuff, why do we need synchronization?
