What coding questions are asked for TSE L2 interviews at HackerRank or similar SaaS companies?

Hi everyone,

I'm preparing for a Technical Support Engineer (L2) interview at HackerRank and was wondering what kind of coding questions are typically asked.

If you've interviewed at HackerRank or similar SaaS companies , I'd really appreciate your insights.

Specifically:

What coding questions were asked (Python/Java/JavaScript)?

Were they LeetCode-style (easy/medium), debugging, or implementation-based?

Did they involve APIs, JSON, log parsing, file processing, or data structures?

Were there any SQL or scripting questions?

Was the coding round focused more on problem-solving or real-world troubleshooting?

If you remember any example questions, that would be very helpful.

Any interview experiences from 2025–2026 would be greatly appreciated.

Thanks! 🙏
