My experience of interviewing with Microsoft in COVID lockdown.
Hiring event contains 4 rounds of 45 mins. each with 15 mins. break after each round.

1. Interviewer gave 1 scenario related to database and asked for different cashing techniques. Later he asked to implement "Least Frequently Used" caching mechanism using Codility.
2. 1 behavioural question and 1 coding question. Problem was based on "Displaying chars from string which appear odd number of times in whole string." Later asked how can the solution be useful for large input data such as book content.
3. Digits of 2 numbers are represented by list. Need to add 2 lists and display the digits from number in result in list format.
4. Something related to consumber supplier problem. It included design and coding.
