The epitome of a horrible OA process.
Mental math, brain teasers, corny and random questions, outdated and horrible testing software.
Coding portion - random questions with minimal description and no testing, all would take a decent amount of time to implement, quit after 1st one cuz it was so boring. Around easy-med leetcode.
Like their medical software, their interview process is extremely outdated and horrible - from their interview I already know that the work I would be doing if I were hired would be boring.
Take the OA if you want, but thank me if you don't cuz you would be saving 2 hours for better things.
