Round 1 was an interview with HR to screen you - pretty standard.
If successful, round 2 was a collection of 3 interviews from different employees within the business - SW manager, SW team lead, Product Manager, Lead Designer. The people will obv vary depending on the role you apply for. Good questions from people who know their roles and the business well and have a very good understanding of delivering SW in an agile environment.
