I applied online. The process took 1 day. I interviewed at EduChat (Bengaluru) in May 2017
Interview
It was very easy. They just asked problem solving questions and were interested in knowing the formulation than your syntax. There were a few questions on algorithms and a few to test your SQL. The final round with the CEO was more managerial than anything else, although he did enquire about SQL proficiency and ability to Ramp up.
