The interview questions are not formalized, they ask whatever they feel to ask at that moment, some tie the interview will take a days time. They will take around 2 months time to revert.

Made me wait for hours, then one by one the team arrives after 2 hrs, first HR followed by some departments heads, all go smoothly until the CEO arrives. CEO only go on to speak garbage and theories which make no sense at all. Looks like a waste byproduct sitting there.
