OneSignal Interview Questions
& Process

The interview process was split into several steps. First, I had a phone call with a recruiter where we talked about my experience and what OneSignal was looking for. Next, I had a call with one of the engineering managers. We spoke for about an hour and covered my background, the kind of work I'm interested in, and what I'd be looking for in a role. After that, I was invited to two technical interviews. These were more hands-on — I was asked to share my screen and work through a coding challenge or task that was given at the start of each session. I didn’t know exactly what the tasks would be ahead of time, but I was told the general area they’d focus on (like front-end or in-memory databases), which helped me prepare a bit. The final stage was a “virtual onsite.” I had the option to do it remotely and split it over two days, which was really convenient. It involved a series of interviews with different team members from engineering, product and HR. Everyone I spoke to was friendly, and the interview challenges were clearly explained. Throughout the process, the recruiter regularly checked in to see how things were going and was happy to adjust the pace of the interviews based on my schedule, which I really appreciated.

I went through five rounds of interviews at OneSignal, which included a final presentation. The beginning of the process was good, but it got disappointing at the end. After the last round, they said I'd hear back by the end of the week. I followed up, but they went silent for over a week past that. It felt dismissive after all the work I put in, especially for the final presentation. I ended up withdrawing my application because I got another offer. I told them my feedback hoping they'll be more transparent with future candidates. It's a shame because I was really excited about this job. I hope OneSignal uses this feedback to get better at communicating with candidates.

Started with a recruiter screen, then an internal recruiter screen with the same questions. Next was a live coding test with a developer and a live platform test with a platform engineer. Then, I interviewed with the head of platform engineering and finally with the head of people. I had to keep asking for feedback and to move forward because it was never given. After all that, they said I didn't have enough technical seniority, even though I passed the technical assessment, four weeks later. The hiring manager seemed really tired and annoyed in one of the last interviews, which was a bummer. I wasn't shocked to get rejected, especially after having to ask for feedback again.

Recruiter reached out about a role, went for a screening, it was a fit. Then a hiring manager chat about motivation, why move companies, interest in OneSignal. Recruiter said it went well, then got a take-home. Did the take-home. Another hiring manager chat. Met the team, 1-on-2 scenarios 3-4 times, each an hour. Then interviewed with the VP and COO, both went well. Final chat with the hiring manager again. This whole thing took 7-8 weeks. Lots of unnecessary interviews. Kept interested because they kept saying I was the strongest candidate, the team wanted me, and could see me as a manager. Felt lied to about why I wasn't hired, got a generic "exec team hasn't chosen anyone because it isn't the right time". Ticked every box and was told so by everyone. They tried to hire my colleagues shortly after, some less qualified. Wouldn't want to work for a company that lies, inflates you, deceives, wastes time, and offers disrespect.
