Vanguard Data Analyst candidates describe a process that moves from a light screen into practical analyst work. One candidate had a basic phone screen about their background, then a one-hour HackerRank-style test with roughly 10 to 15 questions. They recall mostly basic SQL, one more intermediate problem, and multiple-choice statistics and hypothesis testing, and they ran out of time. A Senior Data Analyst candidate also reports a simple SQL HackerRank, so timed SQL practice is a sensible first priority.
The case study appears to carry real weight. One candidate says it was meant to take 4-6 hours, took longer, and had to be turned into a PowerPoint. They then walked through it in a technical interview, followed by a behavioral interview on why Vanguard, leadership, conflict and innovation. The Senior Data Analyst candidate presented an A/B case study to a senior manager. A third candidate describes the next step after the assessment as a consulting-style case on profit, metrics and whether performance looks good or bad.
For the Senior Data Analyst, A/B testing fundamentals were prominent: statistical significance, p-values, power, whether to launch after a failed experiment, and how to test when user-level randomization isn't possible. One candidate also reports a rushed remote round with basic pandas and SQL on screen share. One candidate describes slow and disorganized communication, so plan your time and follow up politely. Reports are few, so expect variation by team and level.

Real interview reports from people who went through the Vanguard process.
The first thing that stood out to me was how fast the process moved from a basic phone screen into a pretty practical skills test. My initial phone screening was straightforward and mostly about my background, with the interviewer asking simple experience questions like how many years I had been working. After that, I was sent a data analytics assessment that focused on data concepts and writing SQL to solve data issues. That part felt more hands-on than the phone screen, and it was clearly meant to check whether I could actually work through common analyst problems rather than just talk about them.
The assessment itself was a one-hour HackerRank-style test with about 10 to 15 questions. I remember four of them being basic SQL, one being a little more intermediate, and I ran out of time before finishing it. The rest were multiple choice questions on statistics, hypothesis testing, and some basic math. If you get past that stage, the next round is a case study interview, but it is less about pure statistics and more like a consulting-style business case around profit, metrics, and whether something looks good or bad. I also had a remote interview later that was very rushed and split into two parts: basic pandas questions and basic SQL, with screen sharing the whole time. Overall, the process felt more focused on practical analyst skills than deep theory, and the biggest takeaway for me was to be ready for timed SQL plus a mix of stats and business judgment questions.
Prep tip from this candidate
Practice timed basic-to-intermediate SQL under a one-hour limit, and make sure you can answer statistics and hypothesis testing multiple choice quickly. It also helps to prep for a case-study style discussion about business metrics and whether performance is improving or worsening, since that was the next step after the test.

Synthesized from candidate reports. Individual experiences may vary.
Candidates report a fairly basic first call of roughly 30 minutes in one account. It mostly covers your background and experience, plus behavioral questions such as tell me about yourself and how you handle conflict. Prepare a concise story and a specific reason for choosing Vanguard.
Two candidates describe a HackerRank-style test. One recalls a one-hour test of about 10 to 15 questions with basic SQL, one intermediate SQL problem, and multiple-choice statistics and hypothesis testing. Another calls the SQL simple. Practice speed, since one candidate ran out of time.
A Senior Data Analyst candidate was asked in a video interview whether Vanguard should move forward with a possible campaign. Another candidate describes a consulting-style case about profit, metrics, and whether performance looks good or bad. Expect to reason about business impact, not only write queries.
Candidates report completing a case study and presenting it. One had an A/B case study presented to a senior manager. Another was told to expect 4-6 hours, found it took longer, and built a PowerPoint. The follow-up technical interview walked through that presentation, so be ready to defend your assumptions and methods.
One candidate reports two virtual 45-minute interviews, one technical on the case study and one behavioral on why Vanguard, leadership, conflict and innovation. Another reports a rushed remote round with basic pandas and SQL on screen share. Formats may vary by team, and decisions may take some time.
