Pros
1) I started my career with the start-up and i never felt like am are working for the start up as our Ops head, city head and managers were so professional and friendly working in teaching us the roles just like the well organised company.
2) Your skills and talent will be calibrated with time to time and company will provide you the the best roles/responsibilties which you are really suitable and where you enjoy the job.
3) Ideas of each and every employees are captured, appreciated and implemented.
4) Fastest growing start-up.
Cons
1)If you want to work in a routine job for 9 - 5 like robots and not interested in learning more and growing higher with skills then its not for you, Better find a corporate BPO job and sit over there.
2) Not energetic ?? are you introvert???If yes, then its not a right place for you.
