LeetCode vs alternatives for coding interview prep — honest comparison
by Siti Hajar Omar·May 25, 2026
Spent 3 months prepping for tech interviews this year. Here's what I actually used and whether it was worth it.
LeetCode: The standard. The problem set is comprehensive, the discussion forum is excellent for understanding multiple approaches, and most companies in Malaysia and Singapore align their interview questions to this style. Paid tier is useful but free is enough to start.
NeetCode: YouTube channel + website that curates the best LeetCode problems by topic and provides clear video explanations. Genuinely excellent as a learning companion.
AlgoExpert: Better structured for beginners than LeetCode but the problem set is smaller. Good if you want more hand-holding.
HackerRank: Some Malaysian companies use this for assessment. Worth practicing the format specifically if you're targeting those companies.
Recommendation: NeetCode's Top 150 list + LeetCode discussion forum. That combination covers 90% of what you need for most Malaysian and Singapore tech company interviews.
