There was 2 round of Technical interview each having 1-1 hour. They are hiring for one of it's client.
Technical panel don't know G about Go-Lang. They asked me about my project and I explained each and every single thing in very detail. They emphasize me to explain more about on concurrency and I explain it very well as per my work and project experience, but unfortunately technical panel had no idea about Go-Lang, they couldn't understand.
Actually they are collecting interview questions data, interviewing more number of people asking only about their project experience. So it's not guarantied that you will be selected even if you would have answered every single question very well.
