Interview Process Overview

The interview process at AAK is designed to be thorough yet personable, reflecting their collaborative Scandinavian heritage. Generally, the process moves at a steady pace, starting with a recruiter screening to assess cultural fit and basic qualifications. This is often followed by a hiring manager interview that digs deeper into your resume and specific experience with industrial or business data.

Candidates should expect a practical assessment stage. Unlike some tech giants that focus on abstract algorithmic puzzles, AAK often utilizes a case study or a take-home assignment relevant to their business—such as analyzing a dataset related to production yields or supply chain logistics. The final stage is typically a panel interview involving key stakeholders from IT, business, and potentially R&D, focusing on how you approach problems and fit into the "Co-Development" culture.

This timeline illustrates a standard progression from initial contact to the final offer. Use this to plan your preparation; ensure you have your technical stories ready for the mid-stages and your behavioral and cultural questions prepared for the final panel. Note that the timeline can vary slightly depending on the specific location and urgency of the hire.

Deep Dive into Evaluation Areas

To succeed, you must focus on the specific skills that drive value in a manufacturing and ingredients context. Based on candidate experiences, the following areas are heavily weighted.

Applied Machine Learning & Statistics

• ETL concepts – Basic understanding of pipelines and moving data from ERPs to analytical environments (e.g., Azure).

Example questions or scenarios:

• "Walk me through how you clean a dataset that has significant missing values in a critical column."
• "Write a query to find the top 3 performing production lines by yield over the last quarter."
• "How do you handle data consistency issues when merging data from two different sources?"

Business Case & Problem Solving

This area tests your ability to act as a consultant. You will be given a vague business problem and asked to structure a data-driven solution.

Be ready to go over:

• Problem Structuring – Breaking down a high-level goal (e.g., "reduce waste") into analytical steps.
• Metric Selection – Choosing the right KPIs to measure success.
• Actionability – Ensuring the output of your analysis can actually be used by the business.

Example questions or scenarios:

• "We want to optimize the shipping routes for our raw materials. What data would you need, and how would you approach this?"
• "A factory manager claims a specific machine is causing quality issues. How would you use data to prove or disprove this?"
• "How do you explain to a stakeholder that the model they asked for isn't feasible with the current data?"

Key Responsibilities

As a Data Scientist at AAK, your day-to-day work is dynamic and project-based.
