Copart Test Automation Leaad interview questions

I applied through job portal and got a call from hiring manager for face to face interview. I was taken inside a meeting room where already three ppl were there.Before start of Interview they made me feel comfortable by offering water and also one of the interviwer explained me about the company and in what kind of product they are working. Then my turn came interview started with technical questions like algorithm, Java ,Selenium. Algorithm was really difficult I was given marker to explain in white board, in Java they mostly asked me about collection framework and design pattern. Very Easy questions from Selenium. At the last behavior related questions.
