# Data Structures Interview Ques vs Interview Master

The clearest difference is review sentiment: Interview Master at 88% against Data Structures Interview Ques's 0%. Interview Master also leads on update cadence (fortnightly vs every 47 months) and ratings volume (8 vs 1). Data Structures Interview Ques's advantage is monetization model (free vs free with in-app purchases) and rating (5.0 vs 4.8).

Both are free to download. Data Structures Interview Ques sells 1 one-off in-app purchase and Interview Master sells 1 in-app purchase, starting at $3.99 per month. Whichever you choose, the download price is not the number that matters.

Data Structures Interview Ques holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: Interview Master has 8 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 0% of Data Structures Interview Ques's written reviews are positive against 88% of Interview Master's, so the app with the better star average is not the one people write more warmly about.

Data Structures Interview Ques ships an update every 47 months, Interview Master fortnightly. The most recent releases landed on August 14, 2026 and September 16, 2026 respectively.
