First round of the interview is a 15 minute discussion with the HR. I was asked about my current visa status and about one situation when I multi-tasked.Second Round was a 1 hr hacker rack coding challenge.The challenge was based on any two programming languages that we are comfortable with , I chose Java and Javascript. There were a few multiple choice questions and 2 coding questions in each section. One java coding question was to reverse a string using hashmaps. Javascript had question related to web development , the multiple choice questions were select one or more type questions. The third round was a phone interview for around 45 mins , Where there was screen sharing and the interviewer posted a few code snippets and asked questions based on specific statements in the code , in C ++ there were questions regarding copy constructors and whether a particular statement based on "=" operator would compile or not and in java there were questions based on a base class reference pointing to a derived class object , garbage collection and enum. The next round would be an onsite interview.Unfortunately I did not get through the third round .
