Springer Nature Senior Software Developer (Java) interview questions

Interview process was very long. First when my profile got shortlisted, they sent me a coding test. Once my coding test went thru.. they called me in office for face to face interviews. They took 3 rounds of technical interviews and sent me back saying they will call for interview with US client. I followed up 3-4 times and HR always said she is not getting time slot from US people. One day after a month or so they again called me for interview which was for some other position. Don't know what happened to the interview which I had given already. I still went to their office and gave interview. Again on following up the same reason was given to me and there was finally no response. My notice period got over and I joined another company.
