Plaid Software Engineer Interview Questions
& Process

The interview process was quick and professional. It had 3 stages: an online assessment, an HR chat, and a final interview. The online assessment had two parts to a large, medium-leetcode-difficulty question. The final interview was 3 hours long, split into 1.5 hours of technical questions and 1.5 hours of a manager discussion. The technical part involved three questions, each building on the previous one.

The technical interview process is notably behind industry standards - instead of using standard coding platforms like CoderPad or HackerRank, they gave prompts/ starter code in Zoom, asked candidates write code in their own environment and send it via email, creating an inefficient back-and-forth. The process itself is draining: 7 rounds of interviews, including repetitive technical assessments where alternative approaches aren't well-received. Recruiter consistently showed up 30+ minutes late to scheduled meetings. Most concerning: After completing the entire process, I was informed that even passing all rounds doesn't guarantee placement due to headcount/reorganization issues. Subsequently, received a rejection with zero feedback and no further communication. The experience suggests serious organizational issues. I wouldn't recommend this process even for interview practice, given the excessive time investment required and the quality of technical discussions. Other companies offer much more respectful, efficient, and professional interview experiences. Save yourself time and energy by looking elsewhere.

I rarely write reviews but this one annoyed me the most. Round 1 was a HM call. Round 2 was a 1hr System Design interview combined with a 1hr Coding interview. The System Design interviewer was obnoxious and seemed not senior enough to understand my points. He was also distracted on his phone twice, and I had to get his attention back. The third time, I stopped talking and he didn't notice for a minute, then claimed he lost connection, which I didn't believe. The Coding round was good, but it was annoying that Plaid made us set up IDEs. We were given boilerplate code over Google Meet chat and then asked to email the completed code.
