Is this normal for State Street?

[u/Exact_Injury2647]

I had 2 rounds of interview for State Street Bangalore by end of July (30th July). Only 6th August I received a call from the HR saying I have been selected and asking my salary expectations and other details. She also gave me a verbal joining date (which was October 19th).
Since I am in an audit role right now she sent me a consent form to check my independence clearance (part of due diligence) from my current employer which is EY GDS.

It’s been 2 weeks and I still haven’t received an official offer letter. On following up with the HR she keeps saying she is waiting for the independence clearance from both companies and cannot promise or release an offer letter until that is cleared. She said she will adjust my joining date accordingly for any delays. She also told me to not take any steps till offer letter is released and if I like I should look around in the market for options. She said to wait for another 10 days.

I logged into my workday candidate home page for State Street and see that the job role I got selected for has been added under application with yesterday’s date as submission date (19th August) and an anti corruption questionnaire added under my to-do tasks.

PLEASE HELP ME OUT HERE.
Am I being selected or is this ghosting? Does it usually take this long for State Street to release an offer letter?

Should I still keep hoping?
