Recruiter reached out on linkedin and took a phone interview. They confirmed moving to the tech screen round. Further they asked me to write written responses to several questions on email besides making me apply for the position. Eventually ghosted after sending an automated email reject. No explanations deemed necessary.

Multiple steps. it's quite a routine process if you look it up on the web. Screening, phone interview, talk to the hiring manager, onsite. very specific to the project and the team you're applying for.
