Privacy Labs interview questions

Very weird interview. It said it's an Android position, but they require you to complete a Go programming assignment first. Which is interesting because I did not mention anything related to Go in my resume, and Go is not mentioned anywhere in the job description, so I think maybe the chance is for others who know Go and Java. However, after one month, I got another email to ask me to complete the assignment. Ok, so I feel maybe I should give it a try, I took all days to study basic Go and finished the assignment, immediately got a decline email the next day with no feedback? Really? The rejection email was sent at midnight, which kind of like an automatic email. I read the only review on this website and saw the guy was asked to use C in the interview? Now I feel the whole interview is just a joke or they were doing some testing. Totally a waste of time.

Boring -- supposed to be interviewing for Golang / DevOps/ Cloud/Orchestration position -- but surprised when asked to code on paper in C?! Garbage business model -- don't waste your time
