Question(s) pertaining to my draft offer and managerial approval

Good morning expats! Hope you’re all doing well

Just wanted to get your views on my job file status, thought it would be better to get feedback from seasoned players.

I have been working for a multinational bank as an Implementation professional for 5+ years and am based in UAE. I received a message on LinkedIn from an HR working for one of the top 4 banks in Doha asking if I’d be interested in an officer role (Grade 4) which is pretty much the same role I’ve doing in my current job. I said yes and the interview took place a week after which was more like a discussion and lasted 10-15 mins. A week passed by and the same HR sent me an email asking for an HR discussion over a phone call and it went well with them explaining the hiring timeline and documents required from my side. I had shared my docs on the same day and received the Draft Offer in 2 days. I accepted and the HR responded to my email stating now they will forward my file further for managerial approval and provide me with Final Offer once done.

It has been 15 business days so far and I’m yet to receive the managerial approval confirmation and final offer. Sent a follow up email to the HR 3-4 business days ago and they responded stating we are still waiting for managerial approval and will update you once we receive it. Now my questions are,

1. Does it usually take Tier 1 companies in Qatar more than two weeks of business days for managerial approvals or is this delay could be related to summer holidays where decision makers are off work often?

2. Does receiving a Draft Offer with job grade and all the other details (including salary and benefits) mean they are serious about my file or is this one of “not to be taken seriously” case?

3. The HR is being responsive and haven’t given me red flags. Makes me think I’m in hiring pipeline, but I could be wrong. Please feel free to shed some light on this if possible.

TLDR: Got headhunted by a Tier 1 bank’s HR from Doha. Interview and HR discussion cleared. Draft offer received and accepted. Awaiting managerial approval and final offer, though it’s been 15 business days now. HR is responsive with their responses via email. Could the delay be related to summer holidays? Or should I be a bit cautious?

Thank you so much
