The Danger Zone: Top Reasons Candidates Fail
Based on our database of Scania interview outcomes, avoid these common traps:
- Focusing purely on general software trends instead of the auto industry
- Prioritizing speed over safety without justifying the trade-off
- Focusing only on general automotive interest without mentioning software architecture
- Neglecting data integrity when the connection drops mid-upload
