One of the worst interviews I've attended. Totally unorganized and chaotic. Attended for the first round at Tech Mahindra, Electronic City campus. They made us wait at the venue for over an hour and then took us down to a computer room where they asked us to write a program, giving us 2 hours time. The call letter we recieved only mentioned html, css and Javascript but to our surprise, the person responsible for our interview asks us to use react.js and refuses to explain clearly the program we were supposed to write. About 7 people left the room at this time getting irritated. The interview process was conducted in a very unprofessional way.
