My interview at Sendinblue was arranged by HR and conducted by a Lead Engineer. The conversation began with an introduction, followed by a detailed discussion about my current work project, including its data flow, backend architecture, and specific components I had worked on. We also talked about my experience with Go and my current tech stack (TypeScript, Python, Rust, Go), along with my reasons for choosing Go or Rust.

For the technical challenge, I was asked to implement the Longest Palindromic Substring problem in Go, and we also had a thorough discussion about its time complexity.

However, the overall experience was quite negative. I felt there were discussions that didn't need to happen, delivered in a gaslighting manner. It seemed like a classic display of seniority where my perspective wasn't genuinely heard, and the interviewer was primarily confirming their own biases and perceptions. I felt the interviewer had a superiority complex, and ultimately, I considered the 60 minutes wasted.
