StoneX Sr. Software Engineer interview questions

I was directly contacted by a recruiter from StoneX. After a screening call, it took another 2 weeks to schedule a technical interview. However, the interview was rescheduled almost a day before the call. The interview lasted 2 hours and covered topics related to SQL Server and C#. It included a coding challenge to build a JSON parser. Following the interview, I reached out to StoneX, but unfortunately, they never responded. During the technical interview, the second interviewer took a break and when he joined back, he was chewing his lunch for a couple of more minutes on a call. It's disappointing and disrespectful to have my time disregarded in this manner, especially when the recruiter communicated purely throughout the process
