Databases

I solved problems on SQL concepts on sql-practice.com and w3resource.com. Focused on JOINS and GROUP BY related queries especially.

Mock Interviews

I gave two mock interviews, where I performed significantly well than before. In DSA problems, the approach was correct but missed in the details. Operating Systems, Projects and AWS related question were handled correctly. The topics that I missed are :

1. Circuit Switching vs Packet Switching
2. Link-state routing vs Distance vector routing
3. Deadlocks in DBMS
4. Which soft skills do I have?

In addition, I managed to write 2 SQL queries correctly during the mock interview within 10 minutes and in first attempt.
