Top 11 Humana Interview Questions in 2025

As a Fortune 40 company, Humana stands at the forefront of enhancing health and well-being, driven by a dedicated workforce passionate about delivering exceptional care. Recognized nationally as a leading health benefits company, Humana’s commitment extends beyond traditional healthcare, embracing technological innovation and data-driven insights.

In a data-driven company, there is a persistent need for data professionals. You might need to know a few things to score a job in your next Humana interview.

1. Initial contact: The first step usually involves an initial contact via email or phone from Human Resources explaining the recruitment process.

2. Video call Interviews: The first significant step of the interview process involves one or more thirty-minute-long video call interviews focused on your experience and behavioral questions. These interviews are designed to confirm your experience and gauge your suitability for the team.

3. Pre-recorded Phone Interview: The next step is a pre-recorded phone interview. The HR tool provides the questions, and you must record your answers. The questions are reasonably straightforward; don’t hesitate to repeat the question if needed.

4. Telephone Technical Interview: This step involves a telephone technical interview, where you will be asked about your technical knowledge and how you applied it in your past role(s) and projects.

5. Behavioral Questions: Get ready for behavioral questions that seek to gauge your response to challenges, team collaboration, and similar real-life scenarios. Don’t forget to detail how you overcame the challenges.

6. Technical In-depth Interview: If you proceed beyond these steps, be ready for an in-depth technical interview that usually involves meeting multiple people - about 6 to 8 at once. Here, candidates would need to answer more complex technical and statistical questions relating to their project experiences, as mentioned in their resumes.

At Humana, coding prowess is critical, especially for roles that delve deep into software development, data analysis, and data science. The statistics reveal that coding questions are a staple in Humana’s interview process, with a staggering 97% of software engineer interviews featuring them. Similarly, data analysts and data scientists are frequently tested on their coding abilities. Here are some representative coding questions to give you a glimpse of what to expect:

1. How would you write a function to find the moving window average of a list of numbers?

Given a list of numbers nums and an integer window_size, write a function moving_window to find the moving window average. Provide examples of your function in action.

2. How would you write a Python function to add together all combinations of adjacent integers in a string?

Write a Python function that adds together all combinations of adjacent integers of a given string of integers named int_str. Provide examples of your function in action.

3. How would you write a function to find the longest common prefix in a list of strings?

Given a list of strings, write a function that returns their longest common prefix. If the list of strings has no common prefix, return an empty string. Provide examples of your function in action.

Data is the lifeblood of modern organizations, and Humana is no exception. With a significant portion of their decision-making process being data-driven, SQL skills are highly sought after, especially for roles like data analysts and data scientists. The interview statistics underscore the importance of SQL in Humana’s recruitment process. Here are some SQL questions to help you get a sense of the challenges:

4. How would you use SQL to answer questions about transactions in the annual_payments table?

We have an annual_payments table. Write SQL queries to answer the following questions:

1. How many total transactions are in this table?
2. How many different users made transactions?
3. How many transactions listed as "paid" have an amount greater or equal to 100?
4. Which product made the highest revenue? (use only transactions with a "paid" status)

5. How would you write a query to find users who are currently “Excited” and have never been “Bored” with an ad campaign?

You work at an advertising firm and have a table of users’ impressions of ad campaigns over time. Each impression_id consists of user engagement values specified by Excited, OK, and Bored. Write a query to find all users that are currently “Excited” and have never been “Bored” with a campaign.

6. How would you write a query to get the total amount spent on each item by users registered in 2022?

You work at Costco, which has a users table with user information, including their registration date, and a purchases table with the entire item purchase history for those users. Write a query to get the total amount spent on each item in the ‘purchases’ table by users registered in 2022.

Probability and statistics form the backbone of many analytical roles at Humana. These mathematical tools help make informed decisions, understand trends, and predict future outcomes. As such, candidates for data-centric roles at Humana are often evaluated on their grasp of these concepts. Here’s a snapshot of the kind of questions you might face:

7. Is the coin fair if it lands on tails 8 times out of 10 flips?

You flip a coin 10 times, and it comes up tails 8 times and heads twice. Based on this outcome, would you consider this coin to be fair?

8. What is the difference between covariance and correlation?

Explain the difference between covariance and correlation. Please provide an example to illustrate your explanation.

9. What is the mean and variance of the distribution of 2X - Y?

Given that X and Y are independent random variables with normal distributions, calculate the mean and variance of the distribution of 2X - Y. The corresponding distributions are X ~ N(3, 4) and Y ~ N(1, 4).

10. What is the difference between covariance and correlation? Provide an example.

Note that this analysis was based on the covariance of random variables, equivalent to population covariance analysis. The same logic still applies for sample covariance since the sample covariance is also an inner product (on the vector space of R^n).

11. What are the logistic and softmax functions? What is the difference between the two? What makes them useful for use in logistic regression?

The logistic and softmax functions are real-valued functions that output values in the interval (0,1). Start by explaining the logistic function.
