Plaid Software Engineer interview: three rounds with a three-hour final

I moved through a tight three-round sequence: an OA, an HR chat, and a final round. The timeline felt fast, and the recruiter was professional.

The OA was split into two parts under one larger question, with difficulty around the medium LeetCode level. The final round lasted three hours, divided into 1.5 hours of technical work and 1.5 hours of conversation with a manager. The technical portion included three questions that built on one another, with each prompt extending the work I had already done.

What stood out was how structured the technical segment felt and how well the schedule held together from round to round. Even though I didn’t receive an offer, I came away feeling that the process itself was organized and fair.

Location: Vietnam. Overall feedback: Positive. Offer status: No offer.
