Citymapper interview questions

The interview process is in 5 steps: 1 - Remote interview with senior member of their Engineering team. 2- Remote interview with their Head of People (EMEA). 3 - Visit to their London office, interview with 4 members of their UK team for 45 minutes each. With 2 whiteboard interviews. 4 - Final interview is a remote call with their Chief R & D Officer. 5 - Call to references & background check then Offer. I managed to pass all of them before being too light on the technical side (it was my first whiteboard, I think I was under-prepared on the insight.) compared to another interviewee. Which is fair. I visited Glassdoor before going into the process, at first I was taken aback from the number of negative experiences and I almost refused (I'm very glad I didn't). The teams at Citymapper/ Via were extremely human and welcoming. The tech team was very helpful and gave me good feedbacks and points to work on for my next whiteboard. :) Overall, it's a very long process which required a trip to London. Despite that, it was probably THE best process I had in weeks! I'm really happy that I got so far and also received so many positive and helpful feedback on my presentation and system design skills. I didn't get the role but I got to connect with talented peers, for that I'm grateful. Thanks for making the process so nice!
