Passed Intuit Staff Interview

Hellointerview.com is the best! I bought the premium subscription, totally worth every penny. Apart from HelloInterview, I did not find any other resource which explains what is expected at Senior and Staff+.

Passed Rippling Senior Manager Interview

By the time I reached Rippling, I had already passed five system design rounds in a row — all firsts for me. That streak simply wouldn't have happened without the structured foundation Hello Interview gave me. The founders clearly know how to teach, not just perform.

Passed Toast Staff Interview

For system design, I went through almost all the core system design questions and fundamentals on Hello Interview. This was actually my second time using Hello Interview to refresh my knowledge, and it helped a lot in rebuilding intuition quickly.

Hello Interview became an absolute game changer, especially for system design... Hello Interview's system design content is outstanding: theory lessons, technology overviews, cheat sheets, practice questions, and especially the videos.

Passed Meta Senior Interview

Hello Interview plays a pivotal role in preparing for this round. Similar question was in 'Peer system design Library' on HelloInterview hence I was able to save time to optimise and answer multiple follow up questions.

Senior & staff roles require depth in system design. You are expected to go beyond classical textbook answers. HelloInterview is a great resource to understand the 'staff' bar.

Passed Meta Senior Manager Interview

I saw few Hellointerview free videos and their free articles on how to prepare for such rounds and I had to buy the premium as I felt it was a great resource for me to understand things and also what I was missingout.

Passed Meta Senior Interview

Practicing System Design on Hello Interview was done by reading and understanding the article first, then build it by doing recall, and practicing going from Entities → APIs → DBs → Scaling/Deep Dives.

Purchase Hello Interview Premium

Many of the resources on Hello Interview are free to use! Premium content is shown on the site with a lock icon if you do not have access to Premium. Hello Interview Premium gives you access to common question breakdowns, exclusive deep-dives, access to our full set of Guided Practice problems, and ranked lists of the most common questions at top companies.

Yes, all future content is included with your Premium access.

Yes. We keep prices the same for everyone and automatically apply any discount you qualify for at checkout — no codes to hunt down, no negotiating. See our discounts page for the current options.

If you have an active premium membership, a credit is auto-applied at checkout when you buy more time. For month or year purchases, that credit is a small fixed amount that stacks on top of any live discount. For lifetime purchases, the credit is prorated based on what you paid and the time remaining on your current membership, so the earlier you upgrade, the larger the credit.

Heads up if you're thinking about starting on monthly and upgrading to yearly later: the top-off is a fixed credit, not a refund of what you paid for the month. That means monthly-then-upgrade costs more in total than buying the year plan upfront. If you're fairly sure you want a year, start with the year.

Much of our content is available completely for free on our website and YouTube channel. Premium content is shown with a lock icon if you do not have access to Premium.

No, this is a one-time purchase. Your card won't be charged multiple times.

Yes! For fixed duration purchases, your access is valid for 1 year or 1 month from the date of purchase, and you will have access to all future problems (and new features) as they are released. For lifetime purchases, you will have access to all future problems and content as they are released.

No, we release new content and problems as we can. You can see recent additions on our changelog. If you want to see a specific problem you can vote for it.

We're adding problems all the time. If you want to see a specific problem you can vote for it.

We do not offer a free trial for Premium. However, we provide extensive free content and access (e.g. you can try one problem of our Guided Practice problems for free), which should allow you to get a feel for what's offered with Premium before purchasing.

Generally speaking, we do not offer refunds for Premium since the additional materials are consumable. Please use the free resources to get a feeling for the content and features before purchasing. In exceptional scenarios, we consider refunds on a case-by-case basis for users who have not consumed the content. Please email support@hellointerview.com for inquiries.
