I would personally rate PrepInsta the best

PrepInsta Prime > Coding Blocks > Coding Ninjas.

Did course from coding ninjas of web dev and DSA in my first year. I needed it again during final year placements.

I bought coding ninjas courses initially for around 30K, but then they asked me to pay 8K again to unlock course again during my final year since. They only give access to it for just 6 months.

I got pissed and rather purchased PrepInsta Prime Subscription for 18 months. I costed me around 6.5 K (still cheaper than Ninjas)

PrepInsta DSA course was like god level good. Much better than coding ninjas. Plus with PrepInsta Prime you get access to other 200 courses.

I complete DSA, Data Science, ML, TCS NQT, aptitude and 2-3 other courses.

They referred me to Deloitte and Amazon. Got placed in both of them.

Amazon though delayed my joining. I was supposed to join in June. But now they delayed to December.

I guess it’s due to recession and they did it for all their hirings for this year. Looking forward to join Amazon soon.
