Ok but you have at least 1 Year of experience in your Primary NOC right ?
If thats true go for the fellowship you want
Keep these in mind:
1. It should be a paid full time fellowship (40+ hours a week)
2. You should be able to get a Letter of Reference, Pay Slips and Bank deposits for this
If you feel you can get these stuff if you get ITA, go for the fellowship
Full time Experience means 30 hours / Week not 40!
