Plaid Customer Success Engineer interview with Quickstart homework and technical questions

I went through two stages. The first consisted of take-home exercises. I had to run Plaid’s Quickstart setup and write response emails to mock customers dealing with specific problems. I liked this part because it made me research what was happening and think through how to communicate in a calm, supportive way.

The second stage was a one-on-one call. I was told it would be a short conversation with a recruiter about my background and career goals, but the latter half turned into a technical interview. The questions were fairly straightforward. One example asked about the JavaScript syntax for a private variable, so the focus was more on understanding the basics than on solving tricky logic problems.

Location: United States. Overall feedback: Negative. Offer status: No offer.
