During this call, which typically lasts about 30 minutes, the recruiter will assess your fit for the role and you might have the opportunity to ask questions regarding the company's culture and the specifics of the role.

Technical Virtual Interview

If you pass the initial screening, you'll be invited to a technical virtual interview.

Expect to discuss data systems, ETL pipelines, SQL queries, and possibly coding tasks related to data engineering challenges. For example, you might be asked, “What is the window function you used before?”

Depending on the specific role and seniority, case studies or take-home assignments focused on data transformation, web scraping, and API calls might also be included in this round.

Onsite Interview Rounds

If you successfully navigate the virtual technical interview, you will be invited to onsite interviews at the AT&T office. This component comprises multiple rounds of interviews, which assess your technical prowess in more depth.

You might undergo several technical interviews focusing on different aspects such as your proficiency against hypothesis testing, probability distributions, and your approach to ad-hoc analysis. Additionally, you may need to present solutions to take-home assignments or case studies provided earlier.
