In this guide, we’ll help you navigate the interview process, from understanding what to expect at each stage to preparing for the Indigo data analyst interview questions you will get asked.

Recruiter/Hiring Manager Call Screening

If your CV happens to be among the shortlisted few, a recruiter from the Indigo Talent Acquisition Team will make contact and verify key details like your experiences and skill level. Behavioral interview questions may also be a part of the screening process.

In some cases, the Indigo data analyst hiring manager stays present during the screening round to answer your queries about the role and the company itself. They may also indulge in surface-level technical and behavioral discussions.

The whole recruiter call should take about 30 minutes.

Technical Virtual Interview

Successfully navigating the recruiter round will present you with an invitation for the technical screening round. Technical screening for the Indigo data analyst role usually is conducted through virtual means, including video conference and screen sharing. Questions in this 1-hour long interview stage may revolve around Indigo’s data systems, ETL pipelines, Excel, and SQL queries.

In the case of data analyst roles, take-home assignments regarding product metrics, analytics, and data visualization are incorporated. Apart from these, your proficiency against hypothesis testing, probability distributions, and machine learning fundamentals may also be assessed during the round.

Depending on the seniority of the position, case studies and similar real-scenario problems may also be assigned.

Onsite Interview Rounds

After a second recruiter call outlining the next stage, you’ll be invited to attend the on-site interview loop. During your day at the Indigo office, multiple interview rounds, varying with the role, will be conducted. Your technical prowess, including programming and ML modeling capabilities, will be evaluated against the finalized candidates throughout these interviews.

If you were assigned take-home exercises, you may also be invited to a presentation round during the on-site interview for the data analyst role at Indigo.

Typically, interviews at Indigo vary by role and team, but commonly data analyst interviews follow a fairly standardized process across these question topics.

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.

What is the average salary for a Data Analyst at Indigo?

What is Indigo’s work culture like?

Based on interview experiences, Indigo’s culture appears to value thoroughness and intensity. However, some have noted a lack of work-life balance, with expectations to work late into the evening and a high-stress environment.
