I would love to help you get completely ready to ace this interview! Before we dive into the core framework of demand and supply planning, I want to make sure I tailor our practice exactly to your background and the specific role.

Could you share the job title or company name from that job posting, and tell me a bit about your previous background in supply chain and when your interview is scheduled?

It's great to meet you! A Supply Planning Manager interview scheduled for next week means we have just enough time to get you razor-sharp.

To make sure our prep is as targeted as possible, I'd love to understand where you are starting from. Could you briefly share your previous experience in supply chain and supply planning so we can tailor our focus on technical concepts vs. mock practice?

It is great to meet you! With your extensive planning background, skipping the basic definitions and jumping straight into the hot seat is exactly how we will make this week count. Since you are targeting a Supply Planning Manager role, the interviewers won't just test whether you know what safety stock is; they want to see how you lead, make high-stakes trade-offs under pressure, and manage cross-functional friction.

To structure your answers beautifully, we will use the STAR method—focusing heavily on your 'Actions' as a manager and the quantifiable 'Results' you delivered. Let's launch right into our first mock scenario. Take a breath, put on your manager hat, and treat me as your interviewer.

Mock Question 1: The Supply Disruption

"Imagine it is peak season for your highest-margin product line. Your primary overseas supplier suddenly notifies you of a critical raw material shortage that will delay their shipment to you by four weeks, threatening a major stockout for your key retail accounts. How do you handle this?"

I'm ready when you are. Tell me about the real-world supply disruption you managed—what was the product, how big was the delay, and what did you do to keep those key retail accounts happy?

That is a classic, high-stakes supply chain headache. A three-week delay during peak season for a critical component is enough to throw an entire manufacturing operation into chaos.

Since you are interviewing for a Manager level role, the interviewer isn't just looking for how you tracked the shipment. They want to see how you mobilized your team, analyzed data to make tough trade-offs, and managed communication with key stakeholder groups.

To evaluate this beautifully, let's break down your story. Let's start with your immediate Actions. How did you assess the impact of this customs delay, and what specific mitigation steps did you drive to protect those high-margin retail accounts?
