Have a consistent study routine. Organization and discipline are key to consistency.
Learning something new is hard. The best engineers practiced too.
Plan first. Code after.
Master the programming language you plan to use.
Don't spend more than an hour on the same problem. Check the solution and try again a few days later.
Simulate the interview. Think out loud and walk through your reasoning.
Roadmap
NeetCode offers a structured roadmap covering all the key topics you need to master for technical interviews — highly recommended as a starting point.

How to approach problems
Don't panic when a problem looks hard. It's normal not to solve everything on your own at first — everyone has their own pace.
Study the theory before jumping into problems.
Don't get stuck on the same question — move on after 50min.
Start with the easier problems to build momentum.
Looking at solutions is part of learning — do it without guilt.
Identify your weak spots. If coding syntax is harder than the logic, do more easy problems until you're fluent in the language.
