Answer no!
For PPL schools anyway. You can't get a job somewhere like oxford but any PPL school should be willing to take you on, mine would and does the almost all instructors that have come and gone from my school were newly qualified most in house. The FI course doesn't make you a good instructor, that comes with practice all schools know this. The course hammers home the basics so your first students will be the guinea pigs allowing you to build experience and confidence in your judgement. Thats why you are restricted initially so that you can't cause to much damage, you will have experienced instructors to advise you and give you guidence.
Hope that helps.
