Fit Round:

The person who conducts this interview is a very judgemental ,rude and biased person. His first concern was about me that I have switched 4 companies in 9 years how we(interviewer) can assume that I will be in apple for long time. I answered that. Post that he did not ask much questions and ended the interview. The person was from semi-conductor background and was working for Apple 10 years. I do understand that any company can look for long term employees but for that you don't need waste someone's time in weekend. As everything is there in my resume so you can reject it upfront. I asked the interviewer that what is the challenge he solved in last 10 years. He got silent for sometime and then he said that his team did 10 person's work by 5 person. So I could understand that this interviewer does not have any skillset or did not do anything good in his entire career. In India most of the company follow the same resource patterns. Also this interviewer is from semi-conductor background and everyone knows the semi-conductor job opportunity in India. I can understand that you have not much option to change job. I would like to request anyone who is going through this post not to accept Apple Interview and waste your time. Apple India team is nowhere comparable with FB or Google. Basically Apple India is not good for Software Engineers.

If anyone is reading this post from Apple please tell your recruiters to contact only people who has stayed in their Company for 10 years and please don't waste other's time.
