EAI Technologies interview questions

First is a video interview, then a call from the HR manager which can be anytime including weekends and without prior appointment. The video interview consists of simple questions with unlimited attempts to answer. In the call, they basically ask the same questions every time to every candidate. They have never reviewed their interview questions. Later there is a technical video interview where they will ask you to code the sum of nodes in a binary tree, preferably Java but they will also give you a choice just in case. They ask only 1 question. And no matter how you answer the question they reject you because basically they are a happy company of 25 who are not planning on hiring any candidates but they are actually promoting their company by conducting fake interviews. Its a waste of time to attend those interviews.

Applied online and in about one week, received an e-mail for video interview. It's on another website and you can record your response answer of some basic concept questions. There is a welcome video telling you the process and questions.
