Couple of days back I attended an interview for MEAN Stack Role. One guy interviewed me. He started with my profile introduction and with some technical interview. I don't know what he was expecting from a MEAN Stack developer. Here are the below questions. 1. Difference between PHP and MEAN I don't know how come a MEAN(Javascript family) developer will come to know the features of PHP. 2. How you will invoke camera in ios application(Ionic app). I just tried to explain the process how to install the camera module and angular provider initialization and etc.. in middle he interrupted me and said i don't what the coding part explain me about the permissions in ios and build process. In my company i didn't get an opportunity for me to generate a build for ios, the same i said to the interviewer. After coming out of the interview. I was just thinking for what role i came for interview and for what i was interviewed. Guys if any one going for interview to this esteemed organization please have a deep knowledge in PHP, JAVA, MEAN, MERN, Metor, ionic+cordova and sooooo on. Since the interview may ask what ever he was interested in despite the role/tech stack that you applied for. All the best guys.
