LinkedIn Project Manager interview questions

Applied for the position through their website. Received an email from one of their recruiters. The recruiter seemed really friendly and provided some background into the position. Went through some standard questions regarding my background and said she would pass my info to the hiring manager to schedule another phone screen. Maybe I misunderstood the recruiter but it felt like they would followup with me to schedule next interview but I never heard from them. I sent the recruiter an email to the recruiter a couple of weeks later following up on status. She said she would check with hiring manager and get back to me. Never heard anything since and never received a rejection email. As such, not a good experience.

Current MBA student, applied to PM New Grad position. Had attended the LinkedIn PM tour earlier in the summer for MBA students in PM roles in the Bay Area. Had an initial call with HR after which a "technical interview" was scheduled with a PM. The technical interview had nothing technical about it, just 4 questions - about myself, my internship projects, why PM-role/why LinkedIn, and whether I'd been involved in a product launch. A 45 minute interview that ended in less than 25 minutes. A few days later I heard back saying they decided not to move ahead with my candidacy. I'm not sure on what basis the decision was made (because nothing was asked that wasn't already on my resume). I spent a week researching the company inside out, had some great (in my view) suggestions and ideas but the interview seemed like a formality to reject my candidacy. Feel let down by the company and the process.
