While it's not a guarantee of being selected, it does indicate that you are still being considered for the position.

It's positive that the HR department reached out to you to provide an update on the interview process. While it's not a guarantee of being selected, it does indicate that you are still being considered for the position. Employers often keep candidates informed of the timeline to manage expectations and show respect for the applicants. It's a good sign that they are keeping you in the loop, but the final decision will depend on various factors. I hope you receive positive news soon!
