My most recent work experience was largely negative. I worked for a company for about 4 months. I was terminated without cause. I was unaware of any issues and when I asked for a reason was told I wasn't a good fit. I had already been applying for new jobs and think they may have caught wind of this (for example someone may have heard a phone call when a recruiter called). I was given paper work stating the reason for my separation from the work was confidential.
In the jobs I'm interviewing for now, I have a difficult time answering why I left the previous job and how it was like working there. I don't mean to rant but for the purpose of this question think it would be useful to give some examples of the disorganization. Where I worked had 300 employees and had been around for awhile. Basic IT systems did not exist and it was not considered a problem. There was no domain; we manually setup each computer and install updates. There was no instant messenger, no ticketing systems. I know some places have issues with copying too many people on email threads but this place took it to a whole other level. Usually entire departments were copied. Management felt this was good in case someone was sick on a given day. There was no value put in streamlining, for example one person would be using Office 2016 on a Mac and wonder why documents looked different to her colleague who opened it on Office 2019 on Windows. Lots of passwords and accounts were shared and this was considered OK.
I would not have taken this job if I had known these things. What should I say in interviews as to why I left my former job? How should I reply when asked "how did your last job end"? Should I say I was terminated without cause, it was a mutual decision, it was a short term contract or something else? Should I just say it was disorganized or give any examples? How do I avoid workplaces like this in the future and tell if they kept up with industry standards? If a job is bad they will probably try to make it sound good in interviews. Though it's been a couple months, I still feel negative effects like burnout from having worked there.
