Whats up with VMWare?

Hey Guys! Just recently got an email offer from VMWare and was hoping to get 2 questions answered. 1. I cleared all rounds of interviews and got a proposed offer on email. My BV has started but I am yet to get an official offer. It has been about 10 days since I accepted their proposed offer. While the recruiter is pretty proactive and has been calling me often on to check in, I'm wondering if this is normal for the offers to take such a long time to "go through their system" and get the required approvals? Am I being strung along? Is this some genius recruitment strategy? OR is VMware just generally slow with stuff like this? 2. Even though I've already accepted, what do you guys think of this offer? I have 8 yoe and this offer is for a Senior MTS in Palo Alto Base - 170k Variable Bonus - 17% RSU's - 100k over 4 years, vesting every year TOTAL TARGET COMP - 223k + Joining Bonus - 10k EDIT: Just got the official offer on 10/24!
