Elsevier Software Engineering Lead interview questions

Generally 4 rounds 1. Hiring Manger 2. Coding Exercise 3. Live coding 4. Cultural Fit Looks I had a tie with other candidates, Had 5th round again cultural fit and leading a team. After a week was told that Interview feedback was positive and been asked to fill few questionnaire and passport details. Also HR informed that waiting for VISA cost approval, post which Offer letter can be sent. Again after a week, HR informed me that Hiring freeze and the position went on hold. Then, I checked internally with my friends in Elsevier, they actually hired someone else. This is really a bad and worst experience ever. Before one week confirmed that interview is positive and the later week hiring someone else and saying that hiring freeze. This is an unprofessional behaviour.
