Is this the right programme for you?
We would rather you pick the right programme than enrol in the wrong one. Here is an honest fit check.
This is for you if
- Working engineers with 0 to 6 years of experience targeting SDE-1 and SDE-2 roles at product companies
- Final-year students and recent graduates preparing for off-campus hiring
- Anyone who knows the basics of one programming language and can attend weekend classes
- People who want structured practice with feedback, not another problem list
It is not the right fit if
- Complete beginners to programming - we share recordings to learn Java or C++ first, then you join
- Candidates who only need a two-week crash course before a scheduled interview
- Anyone looking for guaranteed placement rather than preparation
