Interview consists of a screening by a recruiter. I was discovered by a recruiter for this position. After that I was given an online test to which measured my Linux/Networking/Configuration Management/Scripting Skills. The next few steps were a series of onsite and off-site phone and in person interviews which typically lasted for an hour. I talked to 2-3 Deployment Engineers in the Austin and California offices as well as the Deployment Engineer Manager. Topics covered Openstack, Configuration Management, Operating Systems, etc. Think about your typical high level ops/engineering role questions. I got through all of this over the course of four weeks and was given a verbal offer. I did not receive the offer within the deadline the recruiter initially told me. I waited roughly a week after to give them time. I was given a very nebulous answer that there are a few internal financial and managerial roadblocks that they must resolve before presenting a formal offer. All whilst this time by the way the job is still posted. As a matter of fact it was re-posted several times. I waited a week and a half later to contact the recruiter about the status and I was told that there was a hiring freeze on their end. I am aware that Openstack's presence in the Cloud Computing space has started to dwindle in lieu of AWS and others which has forced Mirantis to change its business strategy over the past few years which could explain reviewers of the company stating mass layoffs and re hirings. This could explain the reason why my offer didn't manifest into anything physical. I feel like I was given the runaround a little bit after verbally accepting something. It could be upper management as mentioned but it could have been a situation where they were fishing for candidates. I interviewed previously this year as well and a recruiter stopped contacting me as well so who knows.

Was recruited through LinkedIn. Had a phone screen with the recruiter, then with a Manager. Was flown out to California for the interview. Great accommodations. Interviewed with a scheduled list of Engineers. They each had their own style of interviewing. From easy and short, to long and difficult. I was given a riddle that I found pretty challenging. I was able to answer it correctly. No spoilers. The riddle is a mixture of personality test and test of wit. I'll be incorporating this next time I'm asked to interview.
