Technical Skills

1. How would you describe your proficiency in Excel?

This question aims to gauge your familiarity with Excel, which is a critical tool for data analysis.

How to Answer

Be honest about your skill level and highlight specific functions or features you are comfortable with, such as pivot tables, VLOOKUP, or data visualization tools.

Understanding SQL joins is essential for data manipulation and retrieval.

How to Answer

Clearly define both types of joins and provide a brief example of when you would use each.

5. How do you ensure data quality and integrity in your analyses?

Data quality is crucial for accurate analysis, and this question tests your approach to maintaining it.

How to Answer

Discuss your methods for validating data and ensuring accuracy.

Behavioral Questions

1. Describe a time when you had to work under pressure to meet a deadline.

This question assesses your ability to handle stress and manage time effectively.

How to Answer

Provide a specific example, focusing on your actions and the outcome.

Example

“In my previous role, I was tasked with delivering a comprehensive report within a tight deadline. I prioritized my tasks, communicated with my team to delegate responsibilities, and worked extra hours to ensure we met the deadline. The report was well-received and led to actionable insights for the management team.”

2. How do you handle feedback and criticism?

This question evaluates your ability to accept and learn from feedback.

Candidates have reported mixed messages regarding outcomes, so maintain a positive attitude regardless of the feedback you receive. If you encounter any ambiguity, don’t hesitate to ask clarifying questions to ensure you understand the next steps.

Stay Calm and Collected

Given the potential for a high-pressure environment, it’s crucial to remain calm and composed throughout the interview process. Practice stress management techniques, such as deep breathing or visualization, to help you stay focused. Remember that the interview is as much about you assessing the company as it is about them evaluating you.

Follow Up Thoughtfully

After your interviews, take the time to send personalized thank-you notes to each interviewer. Express your appreciation for their time and reiterate your enthusiasm for the role and the company. This not only demonstrates professionalism but also reinforces your interest in joining the team.

By following these tailored tips, you can approach your interview with confidence and clarity, positioning yourself as a strong candidate for the Data Analyst role at Indigo. Good luck!

The interview process for a Data Analyst position at Indigo is structured to assess both technical skills and cultural fit within the organization. It typically consists of multiple stages, allowing candidates to showcase their abilities and align with the company's values.

1. Initial Phone Screen

The process begins with an initial phone screen, usually conducted by a recruiter or hiring manager. This conversation lasts about an hour and focuses on your background, experience, and how your skills align with the role. Expect to discuss your understanding of Indigo's culture and how it resonates with your career aspirations. This stage is crucial for establishing a connection and determining if you are a good fit for the team.

2. Technical Assessment

Following the initial screen, candidates may be required to complete a technical assessment, which often includes a take-home assignment or a remote SQL test. This assessment is designed to evaluate your analytical skills and proficiency in data manipulation and analysis. It’s essential to demonstrate your ability to work with data effectively and to showcase your problem-solving skills.

3. Onsite Interview

The onsite interview is an extensive, day-long process that typically involves multiple sessions with various team members.

The onsite experience is designed to provide insight into the company’s mission and culture while allowing candidates to demonstrate their skills in real-time.

5. Final Review and Communication

After the onsite interviews, candidates may receive feedback regarding their performance. However, it’s important to note that communication can vary, and there may be instances where candidates are informed of "positive news" without a definitive offer. This stage may involve additional discussions about internal candidates or further evaluations before a final decision is made.

As you prepare for your interview, consider the types of questions that may arise during this process.

1. How would you analyze noisy and volatile asset price data to ensure accuracy?

You are working at a global trading company analyzing the price of a particular asset over time. The dataset is noisy, volatile, and not guaranteed to be completely accurate. How would you analyze this data to ensure there aren’t any discrepancies?

2. How would you set up an A/B test for multiple changes in a sign-up funnel?

A team wants to A/B test multiple different changes through a sign-up funnel. For example, on a page, a button is currently red and at the top of the page. They want to see if changing a button from red to blue and/or from the top of the page to the bottom of the page will increase click-through. How would you set up this test?

3. How would you verify that an Instagram user is actually a high school student attending the school represented by their sticker?

Say you work at Instagram, and a new feature for high schoolers is about to be released. This new feature allows a user to identify their school and receive an associated sticker that they can use to “rep” their high school on their profile. How would you verify that a user is actually a high school student attending the school, as represented by their sticker?

4. Create a function digit_accumulator to sum every digit in a floating-point number string.

You are given a string that represents some floating-point number. Write a function, digit_accumulator, that returns the sum of every digit in the string.

Example:

Input:

s = "123.0045"

Output:

def digit_accumulator(s) -> 15

Since 
1 + 2 + 3 + 0 + 0 + 4 + 5 = 15

5. What is the probability that a red marble was pulled from bucket #1?

You have two buckets with different distributions of red and black marbles. Your friend pulls a red marble from one of the buckets. Calculate the probability that it was pulled from Bucket #1.

6. What are time series models, and why are they needed over simpler regression models?

Explain what time series models are and discuss why they are necessary when simpler regression models are available.

7. How would you determine if the difference between this month and the previous month is significant?

You have a time series dataset grouped monthly for the past five years. Describe how you would find out if the difference between this month and the previous month is statistically significant.
