I applied through an employee referral. The process took 5 weeks. I interviewed at PolyAI in Mar 2026
Interview
The recruiter was very clear from the beginning what the format would be. The full cycle included the recruiter screening plus 4 interviews and a take home assignment. First interview was with the hiring manager, then a week to complete the design assignment. There were then 2 technical interviews, one for basic python and one for design. The last interview was with a higher up. Everyone was friendly and it didn't feel hard to make conversation.
Very smooth. The first phone screening call with recruiter is great. The second interview was with a team lead, who is super nice.
Overall experience is positive, and the company culture seems very chill.
I applied online. I interviewed at PolyAI (London, England) in Feb 2026
Interview
It was a multi-staged interview including chats with the talent manager and people from the agent design team. There was also a take-home task to design a conversation flow and a small coding challenge. The communication was pretty good, I really enjoyed talking to all interviewers and felt I did pretty well at all stages. Sadly, they chose another candidate in the end. The check-in messages after interviews and the final feedback were a nice touch, I really appreciated it.
