Friend MTS Front End Developer interview questions

Applied to the job through an external recruiter who it turns out had to then forward everything to their internal recruiter who seemingly only books meetings. The people I spoke to in the interviews seemed nice and genuine. Realistic about working practises and generally good people. However there seems to be a disconnect between the job listing, what they're actually hiring for the the questions the guys in the interviews are asking. It felt like the developers want a senior but the person writing the listing and setting the salary doesn't know that. Which was confirmed when I got offered the job for 3k under the bottom end of the listed range despite an actual senior going for 50% more than what they're offering and my recruiter trying to push the top end higher.
