Hologic Technical Support Representative - Diagnostics interview questions

Applied and after one week had the 30 min first interview with HR from UK. One week later got the invitation for the second in person interview at Zaventem office. Ten days later got the invitation for the final in person interview that it never happened because they totally disappear. Very unprofessional, not ethical behavior and missed respect of the candidates, This is happened to me twice, first on 2018 and the second one on 2025.
