So ok here it is, as asked in the comments.

Setting: customer (huge electronics chain) wants a huge migration from custom software to SAP erp, hybris commere for b2b and ... azure cloud
Timeframe: ~10 months….

My colleague and me had the glorious task to make the evaluation result of the B2B approval process (like you can only buy up till € 1000, then someone has to approve) available in the cart view, not just the end of the checkout. Well I though, easy, we have the results, just put them in the cart … hmm :-\
The whole thing is that the the storefront - called accelerator (although it should rather be called decelerator) is a 10-year old (looking) buggy interface, that promises to the customers, that it solves all their problems and just needs some minor customization. Fact is, it’s an abomination, which makes us spend 2 months in every project to „ripp it apart“ and fix/repair/rebuild major functionality (which changes every 6 months because of „updates“.

After a week of reading the scarce (aka non-existing) docs and decompiling and debugging hybris code, we found out (besides dozends of bugs) that this is not going to be easy. The domain model is fucked up - both CartModel and OrderModel extend AbstractOrderModel. Though we only need functionality that is in the AbstractOrderModel, the hybris guys decided (for an unknown reason) to use OrderModel in every single fucking method (about 30 nested calls ….). So what shall we do, we don’t have an order yet, only a cart. Fuck lets fake an order, push it through use the results and dismiss the order … good idea!? BAD IDEA (don’t ask …). So after a week or two we changed our strategy: create duplicate interface for nearly all (spring) services with changed method signatures that override the hybris beans and allow to use CartModels (which is possible, because within the super methods, they actually „cast" it to AbstractOrderModel *facepalm*).
After about 2 months (2 people full time) we have a working „prototype“. It works with the default-sample-accelerator data. Unfortunately the customer wanted to have it’s own dateset in the system (what a shock). Well you guess it … everything collapsed. The way the customer wanted to "have it working“ was just incompatible with the way hybris wants it (yeah yeah SAP, hybris is sooo customizable …). Well we basically had to rewrite everything again.
Just in case your wondering … the requirements were clear in the beginning (stick to the standard! [configuration/functinonality]). Well, then the customer found out that this is shit … and well …

So some months later, next big thing. I was appointed technical sublead (is that a word)/sub pm for the topics‚delivery service‘ (cart, delivery time calculation, u name it) and customerregistration - a reward for my great work with the b2b approval process???

Customer's office: 20+ people, mostly SAP related, a few c# guys, and drumrole .... the main (external) overall superhero ‚im the greates and ur shit‘ architect.
Aberage age 45+, me - the ‚hybris guy’ (he really just called me that all the time), age 32.
He powerpoints his „ tables" and other weird out of this world stuff on the wall, talks and talks. Everyone is in awe (or fear?). Everything he says is just bullshit and I see it in the eyes of the others. Finally the hybris guy interrups him, as he explains the overall architecture (which is just wrong) and points out how it should be (according to my docs which very more up to date. From now on he didn't just "not like" me anymore. (good first day)
I remember the looks of the other guys - they were releaved that someone pointed that out - saved the weeks of useless work ...

Instead of talking the customer's tongue he just spoke gibberish SAP … arg (common in SAP land as I had to learn the hard way).
Outcome of about (useless) 5 meetings later: we are going to blow out data from informatica to sap to azure to datahub to hybris ... hmpf needless to say its fucking super slow.
But who cares, I‘ll get my own rest endpoint that‘ll do all I need.

First try: error 500, 2. try: 20 seconds later, error message in html, content type json, a few days later the c# guy manages to deliver a kinda working still slow service, only the results are wrong, customer blames the hybris team, hmm we r just using their fucking results ...
The sap guys (customer service) just don't seem to be able to activate/configure the OOTB odata service, so I was told)
Several email rounds, meetings later, about 2 months, still no working hybris integration (all my emails with detailed checklists for every participent and deadlines were unanswered/ignored or answered with unrelated stuff). Customer pissed at us (god knows why, I tried, I really did!). So I decide to fly up there to handle it all by myself

So in grade 11 (2 years ago),i had to do something called "job shadowing".basically you choose a profession and you go to a workplace. My cousin (who's in the same SAP industry)got me into this SAP development place.there were like quite a few "developers" but mostly business analysts.they made me learn this (in my oppinion) absolute shit language called ABAP which I found to be mostly glorified SQL . First I had to just create a small program which I did in like a few minutes after my mentor taught me the basic commands but you have to learn alot of module numbers and other shit.and guess what ,I remember I had to end one liners with a damn full stop,seriously fucking irritating.
So,worst dev technology I've worked with ever is SAP.Bad thing is my cousin and my uncle are really trying to take me into that bullshit SAP shit of theirs but I always refuse.will never step my foot into a SAP development job ever.

In today's job interview for an apprenticeship for the "Anwendungsentwicklung" position where they specialize in SAP systems (ABAP).

They told me that this position is a new thing in their company and that they want me, once I agree with their contract (which they will send later), to take responsibility for that.

I'm fine with that.

Now comes the part that is bugging me. They also said that the IT manager does not want to be disturbed often, if I have questions.

(I mean I will definitely have some questions. I am an apprentice after all, right? Like why should I join your apprenticeship program, if you refuse to teach me stuff? I can study on my own, as well and not be in your program.)

Just a few times and that's it. They admitted that they do not know much about that position and that I have to learn most things myself. No books and no other resources. They also do not know where the school is going to be yet.

The people in the interview I've spoken to where nice and we made some jokes here and there, but the fact that the company does not want to support me in an apprenticeship is saddening.

I do not know...maybe I'm just too concerned and this is normal day to day stuff for apprentices, but from what I have read about apprenticeships this is not the right thing to do as a company on the internet.

Correct me in the comments, if you think differently.

I will use this company as a last resort.

I’m trying to download the SAP GUI on my Mac to practice and learn ABAP. But the download page redirects to something weird. Speaking of which, is it really hard to get help/resources for something less mainstream and highly specialized like ABAP as opposed to a language like Java, C#.

This post is going to be long and it might not be the platform to ask for it's mainly for ranting yet I wanted to ask a non toxic community.
I'm mainly an ABAP programmer working on an SAP system for my living. No matter how people inside the SAP sphere look at it, it's not exactly cutting edge technology in the world of software development. (and in my opinion it's not even a knife)
As I work in an enterprise environment I have trouble about finding gaps where I can learn newer technologies and thus, I've decided to learn in my free time.
I tend to tilt toward web development as do many I know because I see potential in the GUI which HTML and CSS achieve. And I do believe that combining that with languages such as JS, Python, Ruby, Erlang and Elixir can give way to a healthy experience both in Web development and even desktop development.
In order to avoid overwhelming myself I wish to start with learning web development. Time is not of the essence because I plan to continue working with ABAP for close future, around the next 2 years, and I'm young.
I wanted to ask the community, is there any developer in here that was in the same position and can give out some pointers to the path they took? Is it wise to start my path from HTML5 and CSS3 without looking back to the older ways? Any resource you'd share will be welcomed.
