Allianz Front End Developer interview questions

Took one and a half month of time, three rounds of interview. L1- asked lots of technical questions and examples, still the interviewer was relaxed and discussed approaches. L2- More on the architectural side of programming and other technologies and types of projects that I have worked on. After L2, the position was put on hold. L3- I was interviewed by another team's manager & arch if I would be a good fit in their team, guess they had some budget constraints(which is kind of unexpected from a company of this scale). After a great L3 discussion got a mail that I am not suited for this position, which wasted a lot of time.
