In the dynamic and ever-growing field of tech, companies often grapple with hiring the ‘best fit’ out of a large pool of candidates. The interview process has evolved over the years to filter out unqualified applicants through multiple rounds of technical and behavioral interviews.

For aspiring data professionals, consistently putting your best foot forward during the interview process is pivotal to securing a job in such a competitive industry. In the past few years, different companies and industry experts have created numerous interview guides and services to assist those breaking into the field.

In this article, we’ll compare the services and resources offered by Interview Query vs. DataLemur, two data interview preparation platforms.
