This was one of the worst interview experiences of my career to date. My one suggestion is, if you are truly good technically, do not even consider interviewing here.

My interview was scheduled through an employee referral. Before inviting me, they requested my complete details, including current and expected CTC, and other information. They asked me to come at 9:30 am, hoping to start and finish the interview on time. I arrived at 9:15 am, but my interview didn't begin until 12:30 pm. I was made to wait for almost three hours.

The HR representative seemed least bothered, was casually in the breakout area, and busy eating. Once the interview started (the panel members were very good and welcoming), it felt like a cakewalk. I cleared all four face-to-face technical rounds.

I left for the day as all the rounds were completed. The next day, the HR called to say, "Congratulations! The interview was positive with very good feedback, but we will have one more round with the manager who is based in the US. It's just a formality." I was very happy.

After that day, for another twenty days, no one from the company bothered to contact me. After I followed up a couple of times, they scheduled the manager's Skype round. I thought, "Finally, they have time." On the day of the interview, they cancelled it, stating the manager was busy, and rescheduled it for the next day. The next day, the same story happened, and they cancelled it again. After that, they were again least bothered to at least update me.

Then, one fine day, about eight days later, they called me and said this was the final meet they were scheduling and apologized for the previous issues. I accepted the Skype meeting request.

On the interview day, I was waiting on the call like an idiot, and no one showed up. I was done with the company that day and decided never to join such unprofessional people who do not care at all. It was the height of negligence.

I expressed my frustration to the HR, and their reply was, "Sorry for the inconvenience caused. We will get back to you in 48 hours." It felt like dealing with customer care. And then, after another week, they sent me an email saying, "Sorry, we have already filled the position."

These questions are quite easy, so don't worry about the difficulty level.
