“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+.”
“Use Hello Interview. I can't emphasize enough how helpful their delivery framework and deep-dive videos were.”
“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.”
“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.”
Toast Staff“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.”
“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.”
“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 missing out.”
