I started my career in PHP from a very small company 4 years ago. I took Hadoop online training from Dataflair on Big data Hadoop 2 years ago and to my surprise, with lil hard work with the instructor, I was able to clear Hadoop interview at Cognizant and successfully started my career as Big Data developer. Last year I took Spark online training as well from there and got internally placed in the project for Spark. The training material and method of teaching at DataFlair is very different from other institutes. Thanks to the entire team for providing such a great platform for learning these Big Data technologies.
