First HR interview, then technical challenge that they send to you several days before the technical interview. During the interview you are supposed to code it in front of them. I was given a task to write a CLI tool in 1 hour. I used Go to write it but writing it in Go takes much longer that writing in PHP or Python so I couldn't finish in one hour, but none of the interviewers knew Go either so the task was supposedly oriented on other simpler languages. No time for any questions. I was told that everything looked good but then got completely ghosted after the technical.
