Hello cf coders , I am preparing for my placement I can solve div2A problems at cf and rarely some problem of div2B .Also like every other coder I tried to get 3/4 stars at codechef but everyone suggested codechef doesnt help that good for coding.So I am now at leetcode.

So could any possible Indian coder suggest how should I prepare for my placement coding rounds (belongs to Tier-3 clg) I am active at Leetcode.Plz guide.
