First I was contacted by a recruiter in LinkedIn. After a short screening call the recruiter scheduled another call with the head/manager of SRE/DevOps team. That was not a real interview. I was asked about my experience, some experience-related questions: how did I implement and what do I think about this and that, what do I like and so on. After the interview a was given a technical task. The task takes about 3-4 hours to implement and you have to upload it to a shared Dropbox folder. Several days later I uploaded the solution and sent a notification e-mail. I couple days later the Dropbox folder with my solution has been unshared. I did not get a follow up from the recruiter or the tech lead.
