I finished my virtual onsite 2020 on March 24. Got the result today. No offer.
I requested for Feedback so I can prepare better for my future interviews. I was told that they can't share those details.

Questions :

Filling the rain water in a bar chart
Anagram finders in a list of strings
Adding two binary integers

Implement a bot that downloads millions of files from thousands of nodes without detection

Finished 400+ LC 250 Easy+ 150+ Medium 10+ Hard

I have 10 years of experience in Engineering.

I am devastated as this is my 4th onsite in last 5 months. I'm not sure what I am doing wrong or if I lack the skills to clear an engineering interview with the top 5.
