I would recommend Petaa Bytes to anyone who is serious about pursuing a career in BigData -Hadoop, MongoDB, Python or taking their IT skills to the next level. I took the course work with Instructor Shrikanth, and he was super knowledgeable and fantastic! There were three students (including myself) in the class and he taught the class at a pace where we were all able to grasp the material and understand. If any of us got stuck on something, he would stop and help us work out our problem before moving on. The classes were well paced and questions were encouraged. It is totally hands-on.
