Contacted first by an external recruiter, the process with them took one month and a half (a Skype interview and face-to-face interview). Very pretentious and arrogant attitude toward the candidate, also it looked like they never read your cv before the actual interview took place. They asked silly and generic questions (to which one must have replied with the "right" specific answer they already had in mind...). Unpleasant, unprofessional, unethical. No feedback after the interview as they promised earlier in the process.
