I can share my experience. I applied for NT Tube in August 2022 and went through a lengthy interview process that extended into November 2023. In December, I received an email congratulating me on being successful, but then to my surprise, another email arrived within a week stating they wouldn't be opening the vacancy until mid-2024. Frustrated by the wait, I decided to take their part-time weekday evening position. Unfortunately, my application is now stuck in the reference stage, and I have no idea how long this delay will last.
