Details

Round 1: Hiring Manager

I discussed two past projects and their specific details. The hiring manager provided an overview of what to expect in the subsequent interview rounds.

---

Round 2: Hiring Manager

The hiring manager asked the following questions:

• What is Recall?
• What is ROC, AUC?
• What is P-Value?
• How to do RCA if a service's SLA drops, and how to improve it?
• Tell me about a time you worked with a difficult person.
• Tell me something counter-intuitive you learned.
• What is hypothesis testing? What are Type 1 and Type 2 errors?

Round 3: Senior TPM

The coding assessment focused on basic data manipulation. I spent time preparing for DFS/BFS questions based on interview preparation materials I found, but the actual questions were more fundamental. I had 30 minutes to complete 12 questions, and completing them wasn't mandatory, but explaining my approach was.

I presented a project I had led. Approximately 30 TPMs from different levels at Snap attended and asked questions.

Round 5: Daily Operations

The interviewer, a TPM from another team, asked:

• Have you had any cost-saving experiences?
• How do you assess project ROI?
• How do you make teams accountable?
• Have you encountered situations where SLAs decreased, and how did you resolve them?

Round 6: Product Sense

The interviewer, an engineering director, primarily discussed the product I was currently responsible for. Questions included:

• What are the metrics?
• Have you encountered situations where the data looks good, but leadership is not satisfied, and how did you lead the team to resolve the situation?

I went into details about my current work.

Round 7: Software Knowledge

The interviewer asked:

• Tell me about an engineering project you were hands-on with, from end-to-end development.
• What is the ML Lifecycle?
• Suppose Snap wants to create a content recommendation service. Apply the ML Lifecycle you just mentioned and explain what would be involved.
