the interviewers were unprofessional and displayed bad practices which was indicative from the questions they asked, they insisted on wanting someone that used anti-patterns like they used, they relied on ad hoc non-versioned sql queries which is non-compliant for a regulated environment. they asked me other questions as well which showed that they did not have basic understanding of immutability or the concept of data transformation. they also called 2 hours before the scheduled time of interview which was odd. in fact, they could not even provide an exact interview time, they provided a time range, and never even bothered to call within that time range.
