Moving to UK as NHS spouse dependant – visa + jobs advice

About me:

• From India
• MBA Finance
• 2 years work experience

I want to know:

1. How to apply for dependent visa?
2. How long does it usually take?
3. What jobs should I target in the UK with my profile? (finance/admin/banking/insurance etc.)
4. My wife earns around £3,000 net/month — if I also get a job, can we save well in the UK?

Would appreciate advice from people with similar experience. Thanks!
