Senior Software Engineer Interview Experience - London, United Kingdom

June 5, 2026
Negative ExperienceNo Offer

Process

I applied through a recruiter. The process took 2 weeks.

The process that I participated in was divided into:

  1. Screen with HR
  2. "Pair Programming w/ 2 devs" (Implement a Token Manager). It is not an algorithm test
  3. Feedback

I didn't receive an offer. In pair programming, don't expect to be a real pair programmer or a collaborative implementation (the "How you work together with us to solve the problem" is a lie). Even if you led the pair to the right solution, if they prompt you with questions, you are already out. The red flags pointed out by the dev team don't make any sense, although it is a pair programming and the right approach/solution was given, red flags were pointed out like:

  • Asked for clarification about the problem (I should not ask)
  • Implement the right problem when there is a question about missing parts during the interview (Except in pair programming)

Although I had helped Auth0 implement their Token Manager and had implemented it multiple times, according to the Wise devs, because I asked for clarifications and was prompted by them with questions about the implementation, even providing the right solution during a PAIR-PROGRAMMING, they classified me as a JR~MID Developer (11 YoE in big North American companies).

So I do believe that:

  1. They are not hiring anyone
  2. Or the position was already closed by another candidate BEFORE the test
  3. Or they are looking for a unicorn
