● We believe that the role of an engineer at a typical product company in India has to evolve from just working in a request response mode to something more involved.
● Typically an engineer has very little to no connection with the product, its users, overall success criteria or long term vision of the product that he/she is working on.
● The system is not setup to encourage it. Engineers are evaluated on their tech prowess and very little attention is given to other aspects of being a successful engineer.
● We don’t hold appraisals as we don’t believe that evaluation of work and feedback is a constant affair rather than every 6 or 12 months. Besides there is no better testament of your abilities than the growth of the product.
● We don’t have a concept of hierarchy and hence we don’t have promotions. All we have in Udaan are Software Engineers.
