Align Technology Business Analyst interview questions

First round interview with a recruiter. Second round interview with the hiring manager. Third round interview with the hiring manager and someone from product. Had to put together a slide deck for a new product launch. Also for some reason, had to get people to add recommendations to my LinkedIn profile. I worked on the deck about 2 weeks. I had the third interview and never heard anything back. Even after repeated times trying to contact the recruiter. This was 3 years ago, and I still never heard anything back. I also heard from a former employee that the work environment was not very great either.
