Dataford Avis 

used it for my amazon DS onsite. my weakest spot was experimentation so i basically grinded every A/B testing question in the amazon plan. stopped memorizing definitions and actually practiced explaining sample size and holdout groups out loud.

was prepping for my meta product analyst onsite and lowkey spiraling about the metrics trade-off round. used the meta guide to structure my framework so i wouldn't give a whole yap session. ended up passing the loop and got the offer last week!!

i interviewed for the AI engineer role at revolut and finding legit prep for that stack was giving actual headache 😭 used the revolut AI plan on dataford for like 4 days! the system design questions on LLM evaluation were almost identical to my round 2 screen. definitely worth it fr.

Five stars for Dataford. I used it to prep for product analytics interviews, and the company-specific interview guides were the standout. Instead of grinding through generic questions, I got a clear breakdown of how a given role and company actually runs its process and the kinds of questions to expect — so I could focus my prep instead of guessing. That made a real difference in how confident I felt going in. Highly recommend for anyone targeting product or data related roles.

Life-changing experience. Straight-to-the-point advice that really opens your eyes to opportunities you may have never considered before. Valuable, practical, and absolutely worth it.

I was interviewing for AI engineer roles and finding actual interview questions for these jobs is surprisingly annoying. Most sites still give you generic SWE/ML stuff. found quite a few relevant AI questions here so that alone made it worth it for me

used dataford while prepping for an ML engineer position. really liked that it wasn’t only coding. I got ML theory, model evaluation and system/design type questions too which is basically where I needed the most practice

had a product analytics interview coming up and this saved me a bunch of time tbh. instead of searching glassdoor + reddit + linkedin for what they ask I could just look up the company. spent most of my time on metrics and experimentation after that

got the offer!!! 😭 used dataford pretty heavily the week before my product analyst interview. biggest help was honestly knowing what to expect. I practiced SQL but also metrics/product cases which ended up being like half my interview!!

you type in your target company + role and it literally builds a roadmap weighted by what that company actually tests. no time wasted on irrelevant topics.

my experience has been very positive with Dataford. I found accessing the bank of interview questions initiative and helpful and they do offer webinars to hear from professionals in the field which was great to experience

was lowkey terrified of getting grilled on window functions during my tech screen, but the interactive SQL playground made it click way faster than grinding random tutorials. did three timed mocks back-to-back, cleaned up my answers, and walked out of the loop with an offer. absolutely ate that interview fr!

got a surprise invitation for a technical screen with only 72 hours notice. used the Quick Prep plan to focus ONLY on the top 20 questions for that company. passed round 1 yesterday!

Dataford is an excellent resource for anyone looking to sharpen their technical skills or prepare for their next interview. I especially like the combination of real interview questions, company- and role-specific preparation, hands-on SQL and Python practice, and AI-powered feedback.

The platform continues to evolve with new features while staying focused on practical skills that people can actually use. Whether you’re preparing for a data, engineering, or other tech role, there’s a lot of value here. Highly recommend checking it out!

Constructive guides, intuitive platform. Highly recommend their interview guides

I got the monthly membership to prepare for the account manager role at ADP and it literally had the same questions that got asked! Helped me so much during that interview!! Thanks Dataford ❤️

I used dataford for my front end SWE interview and the questions were very similar to my interview at Visa! Def recommend for anyone practicing their tech interview as it’s the most affordable option out there!!

I had a great experience using the platform to prepare for my swe interview, they offer intensive interview guides for the target company/position and a curated list of questions and mock interviews that made me feel confident going to the interview.
