Behavioral Technical Coding System Design
The interview process was very smooth and well-structured. It focused strongly on real-life implementations rather than just theoretical knowledge. The interviewers were highly knowledgeable and encouraged in-depth, meaningful discussions. There were two hiring manager rounds—one at the beginning of the process to assess alignment with the company, and another at the end, which was a techno-managerial discussion, one DSA, one LLD & one HLD.

Coding Technical Behavioral
It was an on-campus interview process. There were a total of 5 rounds: one machine coding assignment, three rounds focused on Data Structures and Algorithms (DSA), and one managerial round. I managed to clear the first three rounds. For the assignment round, I had the choice of three problem statements, and points were awarded based on how much of each problem I could solve.
Confirmed questions3 questions
- Could you explain Topo Sort?
- What are some other basic DSA concepts?
- The assignment involved choosing from three machine coding problems, with scoring based on the extent of problem solved.

Coding Technical Behavioral
The interview started with a DSA round, which involved a LeetCode medium question. Following that was a React-focused round, which was relatively easy. Then there was a High-Level Design (HLD) round, but the interviewers kept postponing it because they canceled an hour before each scheduled time. The final round was with the Technical Hiring Manager, an in-office meeting where we talked about my past projects and the complexities I've handled. I was ultimately rejected because they felt my background, specifically my current company, wasn't good enough for them. It felt like a complete waste of time since this kind of screening should have happened at the resume review stage.
