NextGen Healthcare Senior Software Engineer interview questions

Started with a nice welcome and the manager was rude while interviewing. I rejected the offer. The company works on the old old old product. Its high time to renew it.

Their job posting for Senior Software Engineer (USA) showed up on a job board. I have over a decade of healthcare IT software development experience in exactly those technologies they were looking for. So I applied it on their website. 3 weeks later, someone from their talent acquisition team contacted me by email and asked for two dates and time slots for a phone interview. I replied with two dates I was available. Never heard from that guy again. And he seems to be a senior member of the talent acquisition team. I just read that ghosting is very common at this company. And recruiters are very unprofessional Moreover, they have their primary development center in India and I suspect that only some non-critical /internal applications are developed in the USA. That's why their behavior is so unprofessional and non serious towards IT positions in the US.
