MobileIron Software Engineer Interview Questions
& Process

The entire interview process was surprisingly short, wrapping up in about a week. It was recommended by a recruiter. Initially, there was a phone screen which felt normal and covered basic Java concepts like 'final', 'interface/abstract class', and involved writing a blocking queue, plus some SQL. The interviewer seemed pleased with my performance. Two days later, I had the onsite interviews, by which time I had already secured two other job offers, something I'd informed the recruiter about. The onsite involved three interviewers, including senior engineers and a manager/director. It was peculiar because their Java knowledge seemed limited to the same basic topics: 'final', 'abstract class', 'interface', blocking queues, and simple SQL. They kept asking repetitive, low-level questions. The manager appeared unconfident and slow to respond. Despite this, I tried to answer patiently. The strangest part was receiving a rejection email while still speaking with the third interviewer. I don't believe my performance was the issue, especially considering I had offers from much better companies. My guess is that my other offers were likely beyond their compensation range. This company seems to be full of unintelligent and impolite people. I wouldn't recommend them unless there are absolutely no other options, or if one is curious about how incompetent a company can be.

Recruiter reached out on LinkedIn. I had another offer from a top tech company, but MobileIron's tech (enterprise cloud security) seemed interesting, so I sent my resume. The recruiter replied that the Hiring Manager wanted to bring me directly onsite. The onsite interview involved algorithm questions (not too hard) and discussions about my work experience. It lasted about 5 hours. The next day, the recruiter called, saying the team was interested in making an offer, but the Hiring Manager thought I'd be a better fit for a more challenging role, so I had another interview (2-2.5 hours onsite). I spoke with the Hiring Manager about the second interview, and he mentioned that he felt the work ethics at the other company I had an offer from were really bad, adding that he wasn't saying this to get me to work for them but as a general observation. A day after the interview, I contacted the recruiter for feedback. He said the team wanted me for the first position, which I accepted. The next day, the recruiter informed me the Hiring Manager decided to hire someone internally, so they were withdrawing the offer they had confirmed the previous day. Luckily, I didn't withdraw my first offer based on this; it would have been a major mistake. Overall, a really bad interview experience.

There were a bunch of technical interviews and then some chats with managers, including directors and even a VP. Honestly, everyone was super nice and made me feel comfortable, which was great. The recruiters I talked to were the best I've ever encountered in my 15+ years of working.
