This article features the top Five websites/platforms for data science interviews to make sure you walk into your interview fully confident and prepared with answers to any questions.
In the world of data analytics, interviews can be particularly challenging. Not only do you need to be able to demonstrate your technical skills, but you also need to be able to communicate your thought process and problem-solving abilities effectively. Thankfully, there are several websites that can help you prepare for data analytics interviews. In this article, we'll take a closer look at five such websites :
Leetcode is a well-known website that provides a vast collection of coding challenges that can help you prepare for technical interviews. The website has a wide variety of questions covering different topics, including algorithms, data structures, and databases. Additionally, the platform provides users with a virtual code editor, where you can test your solutions and see how they perform against different test cases.
One of the best things about Leetcode is that it has a strong community of users who frequently share their solutions to the website's problems. This means that you can review different approaches to solving the same problem, which can help you learn new techniques and best practices.
Leetcode also offers premium features, such as access to interview questions asked by top companies, interview preparation courses, and mock interviews. While the premium features come at a cost, they can be worth it if you want to take your preparation to the next level.
Stratascratch is another website that offers a wide variety of coding challenges for data analysts and data scientists. However, unlike Leetcode, the challenges on Stratascratch are specifically tailored towards SQL and Python. This makes the website a great resource if you're preparing for a data analytics interview that focuses heavily on these two languages.
In addition to coding challenges, Stratascratch also provides tutorials and courses on SQL and Python, which can help you brush up on your skills or learn new techniques. The platform also offers a feature that allows you to create your own custom SQL problems, which can be a great way to practice specific skills that you're weak in.
One of the unique things about Stratascratch is that it partners with top companies, such as Airbnb and Lyft, to provide users with real-world data analytics problems that these companies have encountered. This can give you a taste of what it's like to work in a data analytics role at these companies and help you understand the types of problems you may encounter in an interview.
Datalemur is a website that provides users with curated data analytics questions from top companies. The questions cover a wide variety of topics, including data modeling, data visualization, and machine learning. Each question comes with a detailed solution and an explanation of the thought process behind it.
One of the unique things about Datalemur is that it offers a feature called "Assessment," which allows users to take a timed test consisting of a set of data analytics questions. The platform then provides users with a detailed report of their performance, including areas where they did well and areas where they can improve. This feature can be particularly helpful if you're looking to identify your strengths and weaknesses and focus your preparation accordingly.
Datalemur also provides users with a "Career Path" feature, which outlines the skills and knowledge required to succeed in different data analytics roles. This can be a great resource if you're not sure what skills you need to develop to land your dream job.
Interview Query is a website that provides users with data analytics interview questions from top companies, such as Facebook, Airbnb, and Netflix. The questions cover a wide variety of topics, including data modeling, data visualization, and machine learning. Each question comes with a detailed solution and an explanation of the thought process behind it.
One of the unique features of Interview Query is that it offers a subscription service that provides users with access to additional resources, such as video solutions, personalized feedback on your solutions, and mock interviews. This can be a great way to get feedback on your performance and identify areas where you can improve.
In addition to its subscription service, Interview Query also offers a free resource called "100+ SQL Interview Questions," which is a collection of commonly asked SQL interview questions with detailed solutions. This can be a great starting point if you're new to data analytics interviews or if you're looking to refresh your SQL skills.
Hacker Rank is a website that provides users with coding challenges in a variety of programming languages, including Python, SQL, and Java. The challenges cover a wide range of topics, including algorithms, data structures, and databases.
One of the unique things about Hacker Rank is that it has a strong focus on gamification. Users can earn points and badges for completing challenges and participating in competitions. This can be a great way to motivate yourself and track your progress as you prepare for data analytics interviews.
Hacker Rank also offers a premium subscription service that provides users with access to additional resources, such as interview preparation courses and mock interviews. The platform also partners with top companies, such as IBM and Amazon, to provide users with real-world coding challenges that these companies have encountered. This can give you a taste of what it's like to work in a data analytics role at these companies and help you understand the types of problems you may encounter in an interview.
In conclusion, preparing for data analytics interviews can be a challenging task, but with the right resources, you can increase your chances of success. Websites like Leetcode, Stratascratch, Datalemur, Interview Query, and Hacker Rank can provide you with a variety of coding challenges, tutorials, and resources that can help you develop your technical skills and prepare for the types of questions you may encounter in an interview. By taking advantage of these resources and putting in the necessary time and effort, you can feel more confident and prepared when it comes time to interview for your dream data analytics role.
