I started with a recruiter call that set the pace and guided me through the process. After that, I completed a HackerRank round that lasted about 90 minutes. It included multiple-choice questions, a straightforward DSA problem, and a language-specific API check.

Next was a conversation with an engineering manager about cultural fit, followed by a hiring manager call that led to the next stage. I then completed a paid take-home project, which took roughly 15+ hours, and presented the work. From there, I moved into system design and a pair-coding session.

The rounds felt doable, mostly easy to average, but the process still dragged on for about seven weeks in my case. There was little clarity about what happened after submissions. I kept expecting status updates, but several weeks would pass without hearing anything.

I felt good about my performance, yet the experience left a sour taste. The process was intense and time-consuming, and the lack of specific feedback after the final decision felt unfair.

Location: India. Overall feedback: Neutral. Offer status: No offer.
