English original + your local-language translation

Tech and global multinational interviews are most often conducted in English. For industries like luxury, finance, or pharma, the working language may be local. We show every question in English first — alongside your local-language translation — so you can prep in whichever language your interviewer ends up using.

The Danger Zone: Top Reasons Candidates Fail

Based on our database of CaixaBank interview outcomes, avoid these common traps:

  • Blaming the other person entirely without reflecting on their own contribution or approach.
  • Creating overly large or tightly coupled microservices.
  • Lack of a clear strategy for data consistency across services.
  • Vague answers without specific examples.
