They first sent me an email through their hiring platform.
Although it says you can reply to that email, it doesn't really work.
I had to contact the hiring manager through LinkedIn and send a message in order to tell her that I was trying to reply to her email but it was not getting through.
After a few days, I got a reply and an interview was scheduled. I went to the interview at their headquarter and met with the hiring manager and the manager of the position for about 40 minutes.
Just regular interview questions. When done, I was told to wait for an email to fill out an assessment, but never received it.
