The interview process usually depends on the role and seniority; however, you can expect the following on a Comcast data analyst interview:

Recruiter/Hiring Manager Call Screening

Once your application is shortlisted, a Comcast recruiter will reach out to confirm your qualifications and discuss your experience and skill set. This screening round typically involves questions about your background, work experience, location preferences, and salary expectations.

In some cases, this initial screening may also involve a brief discussion with hiring managers. They might ask surface-level technical and behavioral questions and clarify any doubts you may have about the role and the company.

Expect this conversation to last around 30 minutes.

Technical Virtual Interview

If you make it through the recruiter screening, the next step is a virtual technical interview. This stage usually involves video conferencing and screen-sharing sessions that focus on assessing your technical skills. For the Data Analyst position at Comcast, you can expect questions on SQL, data transformation, data visualization tools (such as Tableau or Power BI), and scripting languages like Python.

Moreover, candidates may be given take-home assignments or virtual tasks related to data analysis, data quality, and data visualization. Additional questions may examine your understanding of complex SQL queries, statistical methods, and your problem-solving abilities with real-world data scenarios.

Onsite Interview Rounds

If you successfully pass the virtual technical screening, you’ll be invited for onsite interview rounds. This typically involves multiple interview sessions with the team, hiring managers, and even senior leaders. During these interviews, expect to be evaluated on both technical skills and cultural fit.

For technical evaluation, questions will focus on your ability to handle complex data sets, develop data models, and create effective visualizations. You might also present your take-home assignment or demonstrate your analytical thought process through case studies and problem-solving exercises.

Typically, interviews at Comcast vary by role and team, but commonly, Data Analyst interviews follow a fairly standardized process across these question topics.

1. Write a function replace_words to stem words in a sentence using given roots.

In data science, stemming is the heuristic of chopping off the end of a word to clean and bucket it into an easier feature set. Given a dictionary of roots and a sentence, write a function replace_words to stem all the words in the sentence with the root forming it. If a word has many roots that can form it, replace it with the root with the shortest length.

2. How would you find the average number of rolls to reach a die with identical faces?

Roll a fair 6-sided die six times and record the results. Write these numbers on another die’s face. Repeat this process, generating a new die from the previous one, until all faces are the same. Determine the average number of rolls needed to reach this state.

To help you succeed in your Comcast data analyst interviews, consider these tips based on interview experiences:
