    SRE Interview

    Average Interview

    Application

    I applied through a recruiter. The process took 2 weeks. I interviewed at Facebook.

    Interview

    45 Minutes for programming, and 45 minutes for linux. Coding was a couple of question, the first one very simple, the second one a bit more tricky with a trick detail to notice by the end. They don't want you using references, but definitely a simple basic reference for your language of choice should be open - because the discomfort of the situation makes people forget simple stuff. The Linux was knowing everything about vmstat in Linux. Every part of the table.

    Interview

    Quick and straightforward. Was contacted by a recruiter, had a phone screening interview and then a 1:1 with a leadership team member. The phone call with a recruiter was more to inform me about the position and then also to verify that my experience was relevant to the position. In both interviews I was given the opportunity to ask questions at the end.

    I applied through a recruiter. I interviewed at Facebook.

    Interview

    Recruiter reached out to me. Wasnt looking at Facebook, but admitted they have had problems in the past with reputation over spying on it users. Several calls were good at first. I was impressed with the team, but still had doubts about the company. Fast forward to a final interview after several attempts to find me a team and was impressed with the managers.. They didnt even tell me I was out of the process and didnt hear back from them. They seem to ghost people and just provide a huge pipeline. I thought some of the people there were great, but overall the company is immoral and couldnt see myself working for a place tha violates civil liberities daily. Thank you Facebook for ghosting me! Back to shady practice and comprosing your dignity for good pay. As a recruiter its pretty sad when you can not share any feeback, yet alone ghost someone. All this stuff about improving the candidate experience is just BS over the Cambridge Analytics scam. Thanks for ghosting me and good luck spying on humanity while claiming otherwise.
