Plash interview questions

I applied online.The process took 4 day. I interviewed at Plash (Bengaluru) in August 2017. The interview process had one round of Technical coding. Very pathetic people. After wasting my whole day. and after saying I did well and they really liked. They called in to say NO because they couldnt offer me even my current salary. Why call someone and waste their time when you do not want to hire them But after after two week they again called me and told that i am selected.
