Ideon Technologies interview questions

I interviewed with a third-party recruiter and, within a week, was connected to the company for an online interview with HR and the hiring manager. The interviewers were friendly, and the questions were general, not overly technical. They promised a response within a week. After no reply, I followed up but got no answer. A week later, I received a rejection email with no specific reason. The delayed response was the main negative; overall, it was a positive experience.
