Wise interview questions

First, they ask you to complete a coding challenge on HackerRank. Nothing to difficult, a few web technical questions and two coding problems. Then, you get an answer from them in the following days and an invitation to a interview on site. I got 3 interviews on site with different people from TransferWise: lead developer, developer, product marketing, VP of engineering. It was really friendly and was almost only quick discussions about technologies I used at work or on my projects, or how I would design an API for a product that does <insert something>. Also, they asked what would I change/add/delete in their product. Finally, I got a interview with the CEO which is part of their process when recruiting full-time employee. Again, it was 30minutes chat about some projects I did, why I wanted to join TransferWise and what I would change in their product.

They were quick to get in touch after I sent my application. HR was very friendly and enthusiastic. I was apologetically warned by everyone I met, that there would be 4 interviews. First interview was with developers. That was a lot of fun - we brainstormed about possible new products and spoke about new trends on the market. The second interview was with the manager to the position I was applying for. He was clearly unprepared and preoccupied with something else as kept taking phone calls during the interview. The questions were standard interview questions.
