It is so challenging for me to prepare online code assessment. I have to push myself hard to prepare, one idea is to work on mock interview on Leetcode.com.
Here are the algorithms I worked on from April 18 to April 22, 2019. I worked on a few random set algorithms, one mock interview I solved two algorithm, second one I did not solve any of those two. I was so surprised to learn the fact that I need to work hard and quickly master those basic algorithms again.
I chose to use those mock interview algorithms to test my problem solving status. I had chance to use those 38 algorithms to help me prepare for online assessment.
Total random set number is 28. I exhausted all random set algorithm in the first two categories, online assessment and phone interview.

Actionable Items
In order to prepare Microsoft online code assessment on April 23, I went over over 20 random set mock interview algorithms on Leetcode.com. I stuck on a few algorithms, easy medium and hard level.
The preparation is also helpful for me to improve my weekly contest performance.
I do not have time to write code for every algorithm. I just choose to spend 5 to 10 minutes and see if I can come out the idea how to solve the problem. And then I terminate the interview and quickly look up the algorithm and solution on Leetcode.com
I put together a github page called online assessment preparation.
Here are the random set with algorithms I worked on.
I use over 15 set algorithms to prepare myself to work on various algorithms.
