Absolutely terrible.
First of all, they pick a few "hards" from Leetcode to ego trip themselves. No racial diversity--all are guys from India (except one white guy) who can't understand the big picture viewpoint. I don't think they even knew what they were asking at one point.
First interview -- Random leetcode question that could've been solved using a recursive solution. No one ever uses a recursive solution in the real world! I told interviewer how bad recursive solutions are in the real world and why they're so slow, regardless of Big-Oh runtime. He tells me to do it recursively anyways. So I proceed and finish. Has smug look on his face. So I do it using a better CPU cache-friendly way in 30 seconds and he's left flabbergasted, like his Leetcode solution didn't tell him about that.
Second interview -- Build a TinyURL clone. Guy trips over himself trying to explain to me REST methods. Tells me I should use a queue like Kafka, and I politely tell him that none is needed even at huge scale since the GET/POST will be so fast when using Redis behind the scenes. I get a smug look from guy when he tells me they instead use Postgres and SQL Server. They wrote their app on relational databases and now they are struggling to figure out why it doesn't scale! So of course they believe moving to microservices is the only solution. NO! Your database is dog slow and that's what slowing down your app! Moving to microservices won't help that. Adding more latency doesn't make your app faster. Architect guy doesn't get it or understand. Just reminds me they're hiring more people to move to microservices so their app can be faster. Okay dude, whatever.
Third and final interview was with a manager from India. Couldn't understand what the guy was saying. But at that point, I was turned off by the "bro" culture that I was determined this was going to be a 'hard pass' for me. The lack of diversity, not just racially but the lack of understanding outsiders perspectives, the lack of empathy or credible questions was a turn off. I simply got the feeling they were going through the motions of interviewing me just so they could try to bring in another H-1B from India.
To make it even better, I went back to my current employer's IT dept who is reviewing our Airwatch contract renewal. I told them about their plans to move to microservices in addition to their lack of diversity and convinced them to cancel our 5,000 seat renewal. We're switching to Microsoft Intune because of this poor interview experience!
