Buymie Senior Test Engineer interview questions

The company atmosphere was great. The interview process was fine. The job requirement is not very close to my level, it's even lower, I know the salary that I mentioned which is my current salary is not in the range of this company, but the title is Senior Test Engineer, which requires even higher ranges. I got a feedback that my tech stack is more domain specific, but I am sure that the company hires cheap tester below a Senior Test Engineer which is a bad practice and they will never find an honest person who has enough experience which they admire.
