I've interviewed with them twice (2016 & 2022), didn't receive any feed back other than a generic decline e-mail. And this was despite promises to the contrary from recruiters, I was ghosted when I asked for it too. I even recall teaching the interviewer some javascript quirk during a coding challenge the first time and solved whatever silly brain teaser question that was asked, with test cases too! Yet zero feedback as to why I was not going to move past that first technical challenge. Disappointing really. EDIT: More on topic, I did really enjoy the MR based technical interview way more than the common coding challenge.
