Mar 27, 2026

Status: B.Tech CSE (Pre-final Year)
Position: SDE Intern (Backend)
Location: Remote / India
Date: Early 2026

**Round 1: **Online Assessment (90 mins)

2 Medium DSA questions (Sliding window and a standard Two-Pointer array problem).

15 MCQs on OS, DBMS, and basic memory management.

**Round 2: **Technical Interview (45 mins)

Started with a deep dive into my resume projects, specifically discussing the architecture of an AI-based recommendation web app I built.

The interviewer asked for a highly optimized Python solution for a maze generation and traversal problem.

Follow-up: Asked to explain the exact time and space complexity differences between using list comprehensions versus generator expressions in Python when handling massive datasets.

Takeaway: Knowing the algorithm isn't enough. You need to understand the underlying memory mechanics of your language (especially Python's garbage collection overhead) when defending your project architecture.
