45 Minute technical interview with an engineer via phone. I could use my preferred language and was mainly focused on solving two short programming questions. Also asked a little bit about past projects and my interests at Niantic.
I applied to Niantic online through their internal portal, and a month later, I received a 30 minute coding challenge to complete online within five days. I haven't heard back from them yet.
I applied through college or university. I interviewed at Niantic
Interview
Initial informational interview to learn about opportunities, followed up by technical and on-site. The initial interview was great, although it did reveal that my skills weren't the best match for the company. I'm more on the design/data side, but they definitely seem to need people with more technical skills (most of the positions were more technical). I think if you have a solid engineering background but also want to learn on the job and expand beyond it, this is a good fit for you.
