During the technical phone screen, I was given a total of 5 SQL and 5 Python questions. For SQL, I successfully completed 3 out of the 5 questions, starting with the easier ones and gradually facing more challenging ones.

For Python, I was able to solve 2 out of the 5 questions, though I couldn’t pass all the test cases for the second one. Unfortunately, I wasn’t able to complete 3 of the Python questions, which ultimately prevented me from advancing to the next round.

However, it was a good learning experience that highlighted the areas I need to improve on. For anyone preparing for this role, I recommend practicing timed coding challenges, especially in Python basics (thinking about all edge cases) and SQL topics like:

• Aggregate functions
• Joins
• CTEs

With consistent practice, you can improve your speed and accuracy, which will better position you to move forward in the interview process.

Overall, it was a valuable experience, and I’m confident that with more focused preparation, I’ll do better next time.

SQL Focus: Aggregate Functions, Joins, CTEs

Python Focus: Basic Data Structures (HashMap, Strings, etc.)
