What is Chromatography? Mass Spectrometry?

2 réponses

You should know this stuff if you're applying for the position. Chromatography separates the sample into it's components based on some property like polarity, size, or chirality of the components. Mass Spec energizes the eluting compounds through electron impact at 70eV, and those compounds will fragment upon relaxation, and each of those fragments has a mass and a charge associated with it, the spectrum of fragments based on the ratio of mass to charge is analyzed by comparing relative abundance of each fragment size.

Hi! As an Amazon employee who interviewed and hired a lot of people here, I've created a guide that has all the questions and winning answers from an Amazonian recruiter perspective.

Rackspace Technology

Why I was out of work for so long before applying to Rackspace

2 réponses

I wasn't fully sure on how to explain my reasons, but I think that It was my fault because I was not prepared, however the understanding of the interviewers helped me move on from the question after giving my answer the best I could at the time. Moins

The key in these questions is to cover the fundamentals, and be ready for the back-and-forth with the interviewer. Might be worth doing a mock interview with one of the Rackspace or ex-Rackspace Data Centre Operations Technician experts on Prepfully? They give real-world practice and guidance, which is pretty helpful. prepfully.com/practice-interviews Moins

How long did you wait from the time you interviewed until your next call?

I don't have any manufacturing experience so I was unable to answer this question which sucked because I was able to answer all the safey, team oriented, decision making, and experience questions. This was the very last question though and it was a HR Person and two supervisors in the panel interview. Moins

Rackspace Technology

Your colleague slipped on a cable and a server got disconnected from it's node, what would you do?

2 réponses

The services running on the server would fail and customers who are accessing those services would not be able to access them...was asked if the customers called what would be your response be,.. the right answer would be: it depends on the SLA with the customers. if 100% up-time is guaranteed, they have to be notified that there had been a glitch and it would be corrected shortly. Moins

Through questions like this, interviewers are mostly trying to test your skillset (and its relevance to the role) as robustly as possible, so be prepared for multiple offshoots and followups. It could be a useful exercise to do mocks with friends or colleagues in Rackspace to get a real sense of what the interview is actually like. Alternatively Prepfully has a ton of Rackspace Data Centre Operations Technician experts who provide mock interviews for a pretty reasonable amount. prepfully.com/practice-interviews Moins
