I applied through a staffing agency. I interviewed at GSA Capital (London, England)
Interview
A lot of recruiters will pitch roles for this company. The process is very long ( two technical interviews, followed by a take at home assessment, one more interview and then a super day). Seemed like they just want to get a grasp on the competition. Rejected me after the second round with the most awful feedback as if I dont know how to code while the interview was easy ( implement a music player, with different edge cases, error handling and so on).
