I joined the online Interview preparation course at Coding Ninjas to prepare for placements. The course was exactly what I wanted: topic-wise lectures with exercises, regular tests, TAs to help if one gets stuck anywhere & mock tests. All the teachers were amazing and made some of the most complex topics like recursion and DP easy. It really helped in my interview preparation and helped me get placed at Samsung and later fetch an offer from Salesforce too.
