Avantages
I started at Netbuilder with just 3 hours of code academy javascript under my belt and within seven months I was a mid-level data engineer/helping with data architect tasks at a household name insurance website. I have since left to become data team lead at world leading ed-tech company, all within a year of my initial interview. This journey wouldn't have been possible without Netbuilder's help, training, support and contacts. All the people who are in the Academy, both as trainers and trainees, are lovely and provide you with the basis of a professional network to call upon when you face technical or professional problems or just fancy some old friends to talk to at industry events. Netbuilder's sales staff are magic workers, who have an outstanding record of getting consultants with limited experience and escalating knowledge into placements that they otherwise wouldn't have had a chance of getting on their own.
Inconvénients
Unlike school or uni, Netbuilder academy will not spoon-feed you the information and training because Netbuilder's clients won't either, if you don't know how to do something look it up or cozy up to the people who do. This might feel uncomfortable for some, but will make you into a resourceful and adaptable consultant throughout your future career. You do have to be very geographically flexible and sometime have to move across the country at very short notice (<1 week) with no relocation package or expenses if you want to commute. Pay is lower than some other big consultancies would start you on, however it is stable and more than you would get on rentacoder.com or other such freelance sites if you were to teach yourself and try to build a career in IT on your own.
