      Senior Software Engineer Interview

      10 Apr 2026
      Anonymous interview candidate
      Helsinki, Southern Finland
      No offer
      Neutral experience
      Average interview

      Application

      I applied online. The process took 4 weeks. I interviewed at Swappie (Helsinki, Southern Finland) in Feb 2026

      Interview

      The interview process is well organised overall. The TA interview was great, they ask the right questions to assess the culture fit. The hiring manager interview was also nice, good chance to learn more about the role, the team, the challenges etc. Everyone was exceptionally nice. The tech interview was 2 parts and is booked at the same time. Which is a bit strange. I guess they wanted to test both coding challenge and system design knowledge at the same time. Which might sound like a good idea for the company, but not for the candidate. After I took the life coding, which imho went pretty well, I went through a system design without knowing if I failed the life coding or not. During the interview I strongly felt that the interviewers have already made their decision, that they've already selected someone else and just pushing through. I do not think this is fair to the candidates. I personally spent hours preparing for both interviews. It was really disappointing to join the final interview and realize no one is really interested in what you're saying because someone else was selected. I wish the process was more honest and transparent.

      Senior Developer Interview

      11 Mar 2021
      Anonymous employee
      Helsinki, Southern Finland
      Accepted offer
      Positive experience
      Average interview

      Application

      I applied online. I interviewed at Swappie (Helsinki, Southern Finland) in Feb 2021

      Interview

      Got an email from their internal recruiter and agreed on a meeting with their lead developer. After the meeting, that was mostly general discussions about company and what they do, I got a technical and architectural interviews scheduled. Technical one was 1 hour of pair programming. The point was to demonstrate that one is able to use tools of a language effectively (in my case it was JavaScript). The architectural one was a discussion with 2 team members about a hypothetical stock app and what kind of decisions I'd make (both front and back end related).

      Interview questions [1]

      Question 1

      App needs to show in near real time stock price. How'd you implement it (high level overview)?
