I found a job that has a job description which is unrelated to my university degree major
I have found a job in marketing although I majored in Accounting at university
In the first statement, you are indicating what exactly is unrelated to your university degree major.
It is the job description, the nature of tasks you are going to be performing.
They are not related to your university degree major.
Also, when using the noun 'major', I believe it is important to specify what major this is: university degree major'.
A 'major' at college or university, is the main subject that the student is studying.
However, 'major' can also mean an officer of middle rank in the army, or it can also 'mean something that is more important, serious, or significant than other things in a group or situation'. You may say: 'This is a major problem for us'.
In the second statement, you have used major as a verb: I 'majored' in accounting.
You have also mentioned the nature of job you have found without being vague: 'I found a job in marketing'.
１つ目の文では、つまりなにがあなたの大学の専攻と関係ないのかを示唆しています。
それは、仕事内容であり、あなたが取り組むタスクの詳細です。
それらがあなたの専攻と関係ないと言いたいです。
また、 major という名詞を使う時、私はいつの専攻かを特定することが大切だと思います。
この場合は、university degree major ですね。
カレッジや大学のmajor は、生徒が専門として勉強する科目のことです。
しかし、major は軍隊の中佐のことや、「そのグループや状況の中で、他のものよりも重要で深刻で、意味のあること」を意味することもあります。
たとえば、This is a major problem for us.（これは私たちにとって主な問題です。）と言うことが出来ます。
２つ目の文では、major を動詞として使っています。
I 'majored' in accounting.
（私は、会計学を「専攻していた」。）
仕事の性質についてもはっきりと言及しています。
I found a job in marketing.
(私はマーケティング分野の仕事を見つけました。）

My job is totally unrelated to my major degree in English!
While at college we must choose a subject to "Major in:". We may find however
that when the time comes for a career choice...our Major "is less than useful".
In fact we might find it is "totally unrelated"
大学では "Major in:"（専攻）を選ばなければなりません。職業を選ぶ際に 専攻が"is less than useful"（役に立たない）と思うかもしれません。
実際にそれが "totally unrelated"（全く無関係な）と思ってしまうかもしれません。
I got a job that isn't related to my major at university.
Well, my job has nothing to do with my major!
When you say that something is not "related" to something else, you are saying that they are not connected. You can use "related" when speaking about family or when you speak about other things that are connected, for example an android and an iphone are related because they are both smart phones.
"nothing to do with" is a phrase we use to emphasize that the two things you are comparing, are polar opposites from one another.
We can use the following expressions to explain that the work/job we are doing doesn't necessarily correspond with the area of study in which we received a degree.
" My job/work/position is not related to my major/degree/area of university study." /
"My job/work/position is unrelated to my major/degree/area of university study."
or
"My job/work/position is not linked to my major/degree/area of university study."
"My job/work/position is not connected to/with my major/degree/area of university study."
'linked' is a more informal expression than 'connected'
It is common in today's society that a lot of people cannot get jobs in the field in which they studied at university, this can be due to high competition, higher demand in other industries, etc. Some people get forced into less desirable jobs because they need to make money.

How is your job?
It is good, going well. And yours?
It is good.
What did you study again?

I hope this helps.
Have a great day.

Notice that in the first two sentences that the synonym to, "not related," is, "unrelated," with the addition of the prefix -un. We can also say that it, "has nothing to do with," to come out with the same meaning.
When explaining that you have a job but it is not in connection or related to your major you can use the above sentence.
Example;
