"StrataScratch has been super helpful. I started with barely being able to finish an easy SQL query to no problem solving most of the medium level in just a few days."

"StrataScratch and the community really helped me prep for the interview — I ended up getting the Data Scientist internship!"

"Love the practice problems and solutions. They're so much to do on the platform that you'll get better over time. I felt so much more confident at work and at interviews because I had a lot of practice with StrataScratch."

"I would like to thank StrataScratch for helping me prepare for my data engineer interviews and I received offers from both Amazon and Meta! It really boosted my confidence level after practicing each of the questions, one of the best data science interview practice websites that I found with a great interface, sample solutions and tagging filters. Thank you again for building such an awesome platform and benefiting the wide data science community!"

"StrataScratch is hands down the best platform if you are preparing for or am working as a data analyst/scientist/engineer. For me, the approach towards solving questions taught by the team on the Youtube channel helped me convey my thoughts clearly to the interviewer while solving the questions. Happy to share that I have gotten an offer from Amazon as a Data Analyst, and I am thankful to the StrataScratch team for helping me reach where I am."

"I was looking for a simple, easy to use interface where I could practice SQL interview questions. The best part of StrataScratch is that you just need to sign up and you have access to various datasets and questions with a user friendly interface. I wouldn't feel so confident tackling SQL questions during an interview without StrataScratch."

"I got feedback from the LinkedIn interview and I'm through the final round, and I kid you not, the feedback included the line "You showed advanced understanding of SQL". So needless to say, I've got StrataScratch to thank for that!"

Oli

"I really wanted to get into data analytics and data science but never really understood the importance of SQL. I found out about StrataScratch and within a few days of using it I wanted to get a premium membership because the questions are really very realistic and I was asked similar questions in my coding and technical rounds. As a result, the platform really helped me gain confidence and helped me get comfortable with SQL queries. Would definitely recommend this to everyone."

"I wanted to say thanks for creating a platform like StrataScratch that emphasizes learning and showcasing the logical thinking process during coding interviews. I'm happy to share that after watching the video solutions and consistently practicing on StrataScratch, I accepted an offer to work as a Data Scientist this summer at Amazon!"

"I received offers from Facebook, Bloomberg, and Zynga. Moreover, I had completed final round interviews with companies like Indeed, Lyft, and Salesforce. I practiced speaking out loud while solving coding questions using the method from the videos, and StrataScratch was just the perfect platform to practice and improve on real-world data query questions!"

"SQL is something that is super important and plays a key role in Data Analysis, and Strata scratch played a key role in mastering my SQL skills. I used to practice 2-3 SQL problems everyday. If I faced any issue with any problem, the discussion forum and solution with clear understanding cleared my barriers. This helped me in passing interviews of multiple companies."

"StrataScratch is awesome! It's the first place I found that allows you to use python in addition to SQL--I already had the content down but it was a great resource for practicing how to structure my coding answer. The Facebook questions were quite similar to the ones that I saw in my Facebook interview today."

"I just wanted to say that I think your platform is really great. I"ve been using it a lot lately, and I wish I found it sooner! I"ve used Leetcode but it"s not the same for the Data Science community. I am strong in SQL but have always struggled with Python, so your platform it"s really easy for me to apply my SQL logic to Python."
