FogHorn Systems interview questions

My resume was sent by a recruiter. The process took about 5 weeks. Phone screen , 4 technical + VP of Engineering on Zoom and in person meeting with team. All the meetings were very respectful.

A recruiter forwarded my resume to this company and attended a phone interview and cleared the phone interview to the next stage of onsite. Onsite had 4-5 rounds of technical and design questions. First a few rounds went well. A few senior engineers asked some average problems and I resolved. Then I met with the manager and got declined a few days after with no reason given. A total waste of time!
