      Site Reliability Engineer Interview

      6 Sept 2018
      Anonymous interview candidate
      Remote, OR
      No offer
      Neutral experience
      Average interview

      Application

      I applied through a recruiter. The process took 2 weeks. I interviewed at Numbrs (Remote, OR)

      Interview

      I was not looking for a change but was approached via Linkedin by their HR and presented with a DevOps position in Zurich or full-remote with an exciting company involved in: cloud only operations, Kubernetes, Docker, Ansible, GO / Java with strong emphasis on full-remote position and pairing with IOS (2 FTE) & Android (2 FTE) developers in Agile manner. Advertised as: * full-cloud company (AWS) * Docker/Kubernetes/kops * Ansible * running GO/Java apps * Couchbase/Cassandra/Postgresql/Kafka Sounded interesting regarding technology stack and structured way of working (as presented) so they scheduled me for a discussion a manager. Discussion went well but started to have doubts as kept on presenting the position as SRE with on-call rotation and local in Zurich. After the discussion I received and assignment of tangential things I was expected to work with and presented as a 2-3h task (not even close to reality considering the requirements and full documentation requested). Completed the task and sent to HR (as requested); after one day received an email that I passed and we can move on to present my assignment. Expected to present my task and discuss it but was asked questions about totally different subjects: Linux IO matters, system calls, CISCO networking (strange in a full-cloud company where you don't even access the networking layer in full), sym/asym encryption, Python (when they use GO and Java). No real issue as everyone has the right to design their interviews and recruit process accordingly but the topics I was facing were not even close to my last years of work experience that was clearly stated on my profile. Overall: not a very good experience as HR/Recruiting presented something & received an assignment on the topic but manager was expecting a different skill set than advertised; I wasted time in 3 calls, a lot of e-mail ping-pong and a Saturday for the assignment for something totally different that what I was advertised.

      Negative experience
      Easy interview

      Application

      I applied online. The process took 3 days. I interviewed at Numbrs

      Interview

      Receive a HackerRank test link. They say that the test may be around 90 minutes. Made the test flawless.. in 20 minutes. Never heard back. Now i understand the bad comments about this company. An SRE test, that is lame like that.. and a HR that does not even reply. In any case after apply.. i read all the company commentary, i wasn't going to accept any offer from this people anyways. Anyways i always enjoy those HackerRank tests, there you can know if you are more smart then the one elaborating the test .. hahaha Just don't waste your time, look for a serious company and not for hungry dogs like this.
