The interview process was full of difficult and exciting challenges, I really liked it. First, I got a very easy algorithms challenge on HackerRank, then a tougher challenge involving parallelism and data structures. After that, I had two technical interviews, where I both described my experience, answered questions about many fields (algorithms, design patterns, security, web application programming, architecture). After that, I had an on-site challenge (which I took remotely :-P), and I had to transform an application written in a programming language I had never seen before. I really liked that one, it was cool and exciting. After that, another technical interview and a culture interview with the CEO. My process was a little atypical, since because of a mistake I had more technical interviews than I should have had. Also, the current process is simpler, some of the challenges have been removed.

Entire process took 2 months from applying online to getting an offer. Stages were: 1. Screening call with Recruiter. 2. HackerRank automated test with 3 code challenges (you can take those in your preferred language). 3. Managerial interview with 2 engineering managers asking questions on experiences, soft skills and values fit. 4. Panel interview with 2 engineers asking questions on software engineering concepts, practices, architecture, design patterns, scalability, etc. Also they ran a simple code challenge with a language of your choice. 5. Cultural team fit interviews. Here you will meet hiring managers from different teams (one manager per call), you'll have as much interviews as teams you'd like to get to know until you find a match for your interests. The interview is a two-way channel where candidate is expected to also ask questions about the team, project, company, etc. Questions asked from managers can vary from assessing soft skills to logical-thinking code challenges. 6. Referrals check. They will ask you to provide contact details of previous managers so they contact them and ask for their feedback about your work/collaboration skills. 7. Offer letter. They will present a formal job offer. Recruitment team were constantly communicating over email and instant messaging service, so despite the lengthy of the process I didn't felt in the unknown at any stage.
