Average Negative Chennai

After a recruiter touchpoint, the process stretched to about four weeks. Week one started with a HackerRank link, and the assessment mixed aptitude-style multiple choice with coding and took roughly 75 minutes. The next week was a pair programming round, which felt more collaborative because the interviewer was attentive and willing to help while I worked through the problem. Week three moved into a meeting with the hiring manager, and the focus shifted toward what I had already put on my resume and whether my background matched what the role actually needed.

The final step was a design-and-fit round that was only about 30 minutes. I remember thinking it was hard to believe I could be rejected after spending weeks making it through earlier stages, especially when the earlier rounds had felt constructive. Overall, the experience left me feeling like the last round didn’t reflect the effort of the process, and it honestly made me wary of end-stage decisions that come out of nowhere.
