I have done my B.Engineering from NSIT,Delhi. I have worked for 3 years in Data science firms on projects involving predictive analytics and Business intelligence using Machine learning. i have taken interviews to recruit business analysts for my firm. I have also appeared in IIM interviews but didn't join any due to personal reasons. I can help you in finding out how to prepare for CAT along with a job. I have also appeared in Civil services exam (stage 2 out of total 3) so I can also guide you towards that.
