I applied through a recruiter. I interviewed at CompatibL in Aug 2020
Interview
3 stage interview process
1. Interview with Head of HR: doesn't have specific questions
2. Technical interview: theoretical questions, e.g. explain S in SOLID, coding questions, e.g. what will this code output
3. Interview with Executive Chairman: doesn't have specific questions, may ask technical questions
I applied through an employee referral. The process took 1 week. I interviewed at CompatibL (Warsaw, Masovia) in Sept 2019
Interview
The recruitment process consisted of two interviews. During the first round I passed math and programming tests. The math test requires knowledge of statistics, mathematical analysis and linear algebra. The programming test contains typical C ++ interview questions. One of the company's employees checked the programming test and asked additional questions. The person interviewing me was very polite and attentive, as was the HR who led my hiring process.
During the second round, I had a Skype interview with my future Team Lead.
