Weird Interview situation

Sounds like you dodged a bullet.

The second team should never have said you had the job without consulting all the interview team first. Seems like a dysfunctional operation that you are well out of.

as that might appear petty. you can ask for feedback from your application

Your experience is sadly nothing unusual.

I've gone through 5 rounds of interviews for an American mulitnational in the IT sector, a role and about a product portfolio which interested me a lot, with the choice of either Dublin or London, and in the end, they've stated that they were not ready to give me any kind of feedback regarding possible next steps, as they "haven't interviewed all the other candidates yet". It would take them another few weeks to do so….. Behind me lie endless amouts of hours of preparaton, product research and doing a ppt presentation.

At this point, after all the rounds of interviews, there is absolutely nothing I can do to move the needle in my favour. During the next few weeks they probably have forgotten what my experience was all about in detail, and would only hire somebody else, based in some kind of emotion. The only sentiment left for me, is they are not happy with my experience and feel the need to still interview other candidates.

It's a very strong sign to me, this ends in a rejection anyway, leaving me to think that I should simply send them an e-mail wanting to withdraw my application. - If they would have been interested in me, they would have hired me by now.

With American mulitnationals you have to be carefull at all times. They are not what they used to be 5 years ago. The products they sell might be good and tempting, but what they call "culture" is either no culture at all, or more and more an Elon Musk copy in terms of culture. They hire you one day, and promise you the world, and fire you the next day and drop you like a hot potatoe, as if you've never worked a single day for them.

With American multinationals in IT operating in Ireland this isn't a problem yet. They still sell you the sexuality, gay/lesbian transgender idea all along and I doubt that's a Trump doctrine, but the California-West-Coast-Liberalism instead.

The issue is more the interview process these days. The candidate can often ask questions as to why this is taking place, but also give the answer him or herself.

Would you really want to work or expect to be hired by a company which draggs you through endless interview cycles and then stalls, with the reason of "not having interviewed all candidates to date"?

You'd hardly work for them, you'd hardly have confidence in them, and they know it, - they've created this atmosphere.

That's the "Elon Musk style culture" or at least part of it I was discribing.

I once interviewed for an American company. Interview day was a mad panic where everything in my "then current" job went wrong so I arrived under-prepared, stressed and not in the mood. The interview was a disaster, but I contacted HR on the Monday afterwards and apologised for wasting both their time and mine.

They got back to me later that year and offered me another opportunity, which went well, and I'm still there, years later.

You won't lose anything by making contact with them, and it might work out in the long term.
