Microsoft | SDE | Redmond | Jan 2020 [Rejected]

YOE: 9 years Location: Redmond, WA. Position: SDE. They level after taking the interview, it was an Azure hiring event.

The loop was very straight-forward. I had 4 interview questions, all of them mixed with behavioral and a coding/problem solving question.

1. Reverse Linked List
2. Given a bag of 100 balls, generate a sequence of draws from the bag. (Basicallty, shuffle an array 1..100).
3. LRU Cache
4. Write an openFile(), that will interact with a File System open() function and minimize the number of times files are opened. Closing the files was not important for the scope of the interview. System.open(): Handle Handle is a cacheable object that you can reuse.

In each of the interview, I was asked to make the process thread-safe. A topic I had never had to think about while preparing. Needless to say, I tanked one interview but was able to tell the other interviewers how I could make my solution threadsafe.

Thank you for the read.
