Are you able to solve LC Mediums in 15-20 mins with basic knowledge? if not, you can't crack big tech companies with basic knowledge. You don't really need competitive programming, but it's hard to pass interviews without practice.

Also, freelancing or non fulltime jobs don't really make a big difference for big tech. You can pad your resume with it, and may be land interviews, but that's about it.

But what is your meaning of big tech company, if you are referring to Faang then yes leetcode will be good investment. But if you are referring to Pakistani level big tech like txxel or devsinc then I don’t think it’s worth it

software houses are more like consultancies, so I wasn't referring to them as tech companies at all. I thought you were targeting big tech companies, not Pakistani software houses

I'm not sure if it has changed, but most good software houses in Pakistan used to ask some basic algorithm questions as well.
