Wise Senior Java Developer interview questions

Had 5 interviews in total Starts with an HR screening Interview , where i was asked about the expected salary and i gave a number of ( 81k ) - Then i had pair programming interview - System architecture design interview - and product interview after all these interviews i received a feedback mentioning that i did really well , bla bla right before my final interview , HR emailed me saying we can only offer u something between (65-55)k without any explanation why it is so different from initially agreed expected salary. when i asked what happened between the process which cause such a difference. HR replied by saying i dont know about it . it seemed HR just wanted to get rid of me without explaining why

I had 3 technical interviews. All of them had live coding challenges. I just passed the first and second interviews and I couldn't pass the last one, so I couldn't get an offer. I was happy with the type of questions were asked during the interview, because they were based on my experience and I tried to propose different solutions to the asked problem.
