THE WORST INTERVIEW EXPERIENCE
If you have a lot of time to waste then please interview with them for time pass.
There 6 technical rounds.
1st round was a telephonic round. This round has some basic questions and what you work on.
2nd round : Technical face to face : Basic ds and java questions.
3rd round : Technical face to face : Problem solving round and design
4th round : Technical face to face : Database , Big data tools
Some of them will ask you to accept a wrong answer , even though your answer is correct.
5th round : Telephonic with Principal Data Engineer from US
6th round : Coding Assignment ( no sample output given ) , first time a took a coding assignment in which there is no sample output given , they will say all vague reasons in the world for not sharing the sample output .
This company simply wastes people time by engaging them in back to back interview rounds. To get the update of any round you need to wait minimum of 2 - 3 weeks. They are extremely unprofessional technical panel who won't even bother to check your assignment until you force them.
They will make you wait for weeks and months saying there so called CTO isn't in the country and the same reason will be given at least 10 times and CTO cannot take phone or Skype interview.
Want to have a worst time waste experience , then interview with them. CTO reason is guaranteed.
