I applied for a Software Engineer position at Atlas Copco through a recruitment agency. The process had four rounds and took a few weeks overall.
Round 1 — Initial interview with the department head. Mostly a screening conversation: my background, motivation, and a walkthrough of the role and day-to-day responsibilities. Afterwards, I received a link to an online test.
Round 2 — Online test with 20 questions covering algorithm basics, .NET and C#, SQL and Microsoft SQL Server, Angular and Vue.js, plus a few simple implementation tasks in C# and JavaScript. Nothing too difficult if you have a decent breadth of knowledge.
Round 3 — Technical interview with a panel of six senior developers. The questions were fairly standard for a senior .NET role — the kind of evergreen topics you'd expect. Think stack vs. heap, how async/await works under the hood, and similar fundamentals. No trick questions or whiteboard pressure.
Round 4 — A one-hour conversation with the regional manager joining from Stockholm. More of a cultural fit and big-picture discussion.
Overall difficulty: easy. If you have solid experience with .NET and C#, you should be fine. The process was straightforward and professional.
I received and accepted an offer. After joining, I've been developing a C# application for automated calibration of industrial tools, which is in line with what was described during the first interview.
Advice to candidates: Make sure your .NET fundamentals are solid — memory management, async patterns, and basic algorithms. The online test is broad (including frontend frameworks), so a general awareness of Angular/Vue helps too.
