Capital One Behavioral Interview Questions and Answers

When preparing for your Capital One interview, don’t forget to practice behavioral interview questions. Here are some sample interview questions to help you with your prep.

1. Tell us about a stressful situation you faced in the workplace and how you successfully navigated through the situation?

Questions like these aim to assess how you will be able to handle the stress that you may face once hired. So pick a situation that was really trying for you and try to highlight how it impacted you. Talk about what you did to work through the situation. Make sure to highlight your strengths that come in handy while dealing with a situation like this so that the hiring managers know that you are calm through stressful situations. 

2. Are you good at multitasking? Give us some examples.

Multitasking is one of the potential skills every employee should possess. Use the STAR method to identify a situation where you had to put your multitasking skills to use. Describe the task you were assigned, the action you took, and the results you received. 

One of the best things to highlight while responding to these questions is to show you handle multiple deadlines, tasks, and requests. The answer should tell the interviewer that as a professional, you are only focused on quality and only quantity. 

3. What is your management style?

Instead of identifying a specific style, talk about how you can adapt to different situations and navigate through situations.z4. Discuss the schemas in data modeling.

There are two: Star schema and snowflake schema.

Star schema has a fact table and the dimension table. It is the simplest data mart schema style. The snowflake schema is an extension of the star scheme, which can add additional dimensions. 

4. Discuss the framework of Apache Hadoop.

Apache Hadoop is based on the MapReduce algorithm used for processing a huge data set. Map filters and sorts the data while Reduce summarizes the data.
