Basic LC style. Easy/Medium and wanted to know your thought process and they emphasize on behavioral questions. Did ok and had positive vibes from interviewers. Round with Eng Directory design questions was kinda tough. Design a CDN service. Didnt do well as I know little about CDN. Didnt provide any details how it should work. Follow-up interview: More behavioral. Asked about Java trivia question which I wasn't able to answer satisfactorily. Question around "static" on classes, functions etc .

Two highly unprofessional guys took my interview. It was looking like they were taking interview first time. didn’t even know how to take interview and how to behave properly during interview. I would request the organisation to give training to these kind of people so that they can learn how to take interviews. Both were very very rude. They had asked to open my webcam but their cameras were off. I think its both way communication, it doesn't mean the candidate is giving an interview should be demotivated while asking questions. It's very easy to sit on the other side of the table and treat the candidate badly without respect.
