I understand you may have already gone to OCS, but you could still read this from there. Maybe someone else will seek out this info as well.
Here's what I understand as an enlisted Sailor who has been recently selected for OCS as an IP and heading there later this month:
In general
Go to OCS.
Go to Dam Neck, VA, for information warfare school.
Follow that up at Dam Neck with a 20-week IP-basic course.
You may also at some point there go to divisional officer school.
Go to first command at shore, where you have three years to get your qualifications. Most officers take about 18 months to get them. It depends on how easily your command is set up to allow this to happen. Keep that in mind when you are thinking about taking those "awesome" orders to the edge of the earth. It will be hard getting your quals at a little base without a lot of mentorship.
Next you will go two years to a sea billet usually on a "small boy," which if you don't know, means a smaller-sized ship, like a cruiser. There you may be given the role of the comms officer or whatever they may need you to be, but probably something like that -- doing comms stuff or IT stuff.
Following that, you will be a lieutenant before leaving that command, and you should at this time begin to think about where you want the Navy to send you to school for your master's. This can be in computer science, space operations, modelling and simulations, etc. You can pick the school of your choice that you get accepted to, and the Navy will pay for it as long as there is funding for the education. This includes private schools like Harvard. IP's for the last few years, as I understand it, have not even taken advantage of all these billets. Some were left unused. Most IP's go to the Naval Postgraduate School, which is pretty awesome too.
Starting here you might go to a carrier and work in the ADP division, which is the IT division basically. You will probably be like a lieutenant divisional officer, who works with a higher-ranking dept. head. You may be assigned to things like performing maintenance "spot checks," where you inspect enlisted Sailors' maintenance duties. Maybe you will run for a position in the officers' wardroom. You might have other additional collateral duties such as the Information System Security Officer (ISSO), which is pretty important. There's a lot you can do.
As your career goes on, you will be expected -- especially utilizing your master's -- to specialize, being sent to a command that takes advantage of your skill set. Probably you'll still be a lieutenant at this point, but you might make LCDR while there. This is part of the reason the IP's can do so many different things after a few years. For example, I want to be in the Navy Space Cadre. Other IP's will want to develop computer programs used Navy-wide. Their advanced computer science degree will help them do something like it. One of my OCS package appraisals was done by the IP captain (now a chief of staff at USINDOPACOM) who created/coded the CANES network system used on many ships today.
Like any officers though, you may have a lot of duties involving sitting at a desk doing paperwork, talking on a phone, managing funding aspects, and so on.
One of the first things you will want to do is get a Milsuite account after you get a common access card (military ID card) and join the IP group. Milsuite is like a military Facebook. All kinds of things are posted there that will help you, including the list of billets and their locations where we can choose to go. The detailers are there, and tons of people are willing to help. Want to get your quals remotely because you went to Antarctica and can somehow still connect through Zoom? Somebody will board you that way. The higher ranking officers answer the call in that group. Officers are also posting documents that have helped me learn a lot of this stuff I've just posted. Plus I met the detailer on there, and he told me this stuff as well. Maybe more. The detailer will reach out to you after so many weeks at OCS asking you what your wishes are for a first command from the list of available. Keep in mind, you get what the Navy needs, but the detailer will take your wishes into consideration when possible.
