A company runs the risk of exposing other hiring biases by using these services, or pre-interview puzzles. If someone solves the problems, yet is not offered an interview, it makes the hiring process seem more opaque and arbitrary, not less. I enjoy programming puzzles and solved the puzzles for Spotify one weekend. I sent in my resume to see what would happen. I was rejected about 2 hours later. I went in thinking it was cool that Spotify was so meritocratic to use programming puzzles as a hiring filter, but came out thinking the process is just totally arbitrary.
