I would recommend ensuring better alignment between recruiters and hiring managers regarding the structure and objectives of interviews, so candidates can prepare accordingly. Providing a balanced evaluation that considers both prior experience and case-based discussions would also lead to a more accurate assessment of candidates.
Additionally, for roles described as international, incorporating a broader range of jurisdictions in the interview process would allow candidates to better demonstrate their full expertise.
Finally, maintaining an open and constructive dialogue during interviews—especially when discussing technical points—can help create a more positive and effective candidate experience.
