Ping Identity Senior Developer interview questions

Interview Process : 1 -> Technical Round taken by one of the principal engineer focusses on DSA ( leetcode - easy/medium), Java concepts and Basic LLD/HLD. Able to answer DSA + LLD/HLD. Didn't answered Java questions since not from java background. 2- Technical Round taken by one of the principal engineer focusses on DSA ( leetcode - easy/medium) with HLD Question. Was able to answer all including contour questions on HLD design. 3 - Hiring Manager Round by Senior Director of engineer focusses on basic experience questions. Got call from HR, was told that all reviews are positive and asked for documents regarding payslips, last offer letter etc. 1 week later got call from HR that my profile is shifted to another vertical that operates in US and would have to give technical interview's again : 1 - Had 30 min discussion with Senior EM of US team, discussion on my experience and some technical questions. - This went really well. 2 - Technical Interview with Staff engineer who has no idea about Time Complexity asked 2 DSA questions. Answered them pretty easily with passing all test cases on leetcode. Couple of days later HR informed that US team had rejected mentining no exp with GCP( I never mentioned in my resume). She mentioned that India team is still considering and will let me know in few days. It's been more than 1month and HR has ghosted me with calls/msgs/email. Not sure what Engg team wants from candidate or even they read resume specially staff engineer. would call myself lucky to not work with that person.
