I applied for a few roles online and received an email back from a recruiter to set up some time to chat and learn more about what I was looking for. I scheduled the interview through their Calendly and then never heard anything when the interview time came. I left them a voicemail and emailed to see if we were still meeting or of we needed to reschedule. I never heard anything back. I eventually looked them up on LinkedIn and realized they are based in India which was odd considering the roles I applied for were based in the US.
I wouldn't be surprised if they're just collecting resumes to farm data to sell. The experience was unprofessional and annoying to say the least.
