I interviewed with Microsoft Azure Team - Hyderabad at Bangalore location .
Overall it was a very bad experience.
It was a bulk hiring process, where they had flown in interviewers from Hyderabad.
Around 40+ candidates of more than 3 years experience had been called.
Everyone was made to wait, and it was too stressful on the candidates - due to the longer wait time, and the panel - due to the high number of candidates to be interviewed.
I had two rounds. Each round was less than 30 minutes and very short. Not sure if it is because I gave the answer rightaway or because the interviewers were not interested (seemed like it).
First round :
1. Tell me about yourself
2. About my current work and job.
3. Then asked one coding question : Rotate array.
He asked to propose any solution first, and then optimise it. I said I have encountered this question and know the optimal solution with O(n) time and O(1) space. He asked to explain solution and then code it.
Once I completed - he asked to do unit test and say few test cases - I did it.
That was it.
Second round :
1. Few questions about my current work and job
2. One coding question : Clone LL with random pointer :
I had not known this question before and I came up with hashing based implementation . The interviewer asked me to write it down, and once done he asked me for alternative implementations.
I suggested two other methods all with O(n) extra space - but he wanted with O(1) extra space. I could not come up with it and was asked to leave.
Other people who interviewed with me got the following questions :
1. Implement singleton design pattern
2. clone circular Linked List
Overall interview experience was very bad. I had to wait for more than 7 hours just to give 30 minutes of interview.
The interviewers did not discuss or participate in problem solving - once I solved the given problem, interview was over. Also they seemed very disinterested in the entire interview process.
HR co-ordination was also very bad. Both interviewers did not have my resume and had some one else's resume - so it was irritating.
Major focus was on array, Linked List and design.
