I did not understand the interview process at all! Either the company didn't want anyone for this role at all and was doing a publicity for the company through an interview or they had already chosen someone(which is highly unlikely because the HR told me I was the first person to be interviewed for the role). Starting with the HR, the first call itself they were late by 10 minutes(never happened before with me). Then throughout the process no reply to numerous follow up emails! Very unprofessional! Finally a call is scheduled for a day in the upcoming week after 2 weeks of 3rd followup email and on the day I had to call on the number to know that they are moving ahead with someone else with more experience. You know they are not serious about the hiring when the interview process feels like a chat, basically talking about irrelevant stuff not related to the role by any means. None of the engineers on the team except for one dove deep into my resume/ask Vision related questions. None except one in the team is a vision expert. Their hiring process is one of the worst ones I have come across in my career. I didn't wait for them after weeks of waiting and took an offer from another company which takes its candidates seriously.
