Risk Management Solutions Senior Software Developer interview questions

I was interviewed for this company about 3 months back. After taking 4 rounds of interviews and 2 round of interviews with the hiring manager, I was told that I was selected. The Recruiter stayed in touch with me for 2-3 weeks and had several calls and emails exchanged. After which they suddenly came back and said that the hiring manager wants to offer me Software Engineer 3 position instead of Sr. Software Engineer., which I declined. They completely wasted my time and disappointed me a lot. I will not recommend this company to anyone,

30 minutes phone screen. The interview is so so. The interviewer lacks direction of what skill sets needed. When asked on some information question on big data environments (Spark), the interviewer could not provide details of it. That is sad
