Snap Product Design Engineer interview questions

Consisted of a recruiter screen, one 1:1 technical interview with a lead engineer, and an "on-site" (remote) vidcon panel with five 1:1 sessions with a hiring manager and four cross-functional team members (ME, EE, ID). The overall process took 12.5 weeks, from application to final interview round. This involved 7 weeks between the initial recruiter screening and the first interview, which only happened after pinging the recruiter to remind them to schedule it. It took 3 more weeks to get the panel on-site together. The discussions flowed well and questions covered many technical and behavioral topics, including very specific design issues related to challenges encountered in their Spectacles glasses, which seemed bordering on "doing work for free" (illegal). The questions should be changedto be more generalized. Most of the interviewers are early to early-mid career, and have worked at Snap for a large portion of their careers so far, so don't have a wide amount of experience in product development, or in interviewing skills. They might want to pre-plan and coordinate their interview agendas for topics, style, and coverage of a candidate's prior projects and skills, which is what I've experienced with other tech companies. The overall hardware development team is relatively small, and the problems facing them are extremely difficult and time-consuming. Combined with big competition in the AR space, it's unclear if they'll be able to compete and launch viable products without growing. Feedback from the recruiting team was within two days. They had other candidates who were a better fit for the role.
