Several rounds: - a phone call with HR to discuss the role and your motivation - a take home exercice where you have to implement a VWAP computation as well as a quizz around the Java language - a 2 hours interview with the engineering team to discuss your solution - a final 1 hour interview with the CTO Although the engineering team was very friendly, higher management lacks professionalism and resources. HR wrote me an email to tell me I had to relocate to Nantes or Rennes if I wanted to join them even though they originally contacted me for a position in Paris.
