PayPal Senior Software Developer interview questions

It was a good experience overall. First round was tough and second round was moderate. Overall there were 4 rounds followed by hiring manager round. Interviewer were leading to a great example.

I applied through online for paypal senior developer role. First round was a hacker earth test. Questions were average(not too easy not too tough) Second round is a programming round with an interviewer ( DS & Algo) asked few questions on circular linked list, queue and dynamic programming. Third round is extended programming round. 1 question is using recursion and the next question is from binary tree ( finding the length between two nodes in a binary tree) Both of the tech interview rounds were fine and interviewers are approachable. The next round is a system design round. This is where things got turned. The interviewer severely lacked communication and I couldn't understand him properly. He gave me a design question to design DropBox. The whole interview seemed one side communication. He doesn't even interrupted me. Then out of the blue after sometime he changed the question to design an autocomplete feature. When i started designing it using trie he then asked me to code it and then asked me to send the design things as screenshot to his email ( without giving his email) Then he left. Overall its a negative experience
