Applied online through their career portal, and got an email back requesting a technical phone interview a week later, with a HackerRank link to be shared with the interviewer. During the phone call, the interviewer asked about my resume and about myself and then moved on to the technical question. He was not that helpful for guiding me towards a solution, he kept coughing a lot (and didn't make a point to excuse himself) and was overall not interactive. I asked him for clarification on some parts, but he did not want to respond. Got a rejection email the day after.
