wǒ yǐjīng shōudào lùyòngtōngzhī le.

已经 means already. It tells you the action has happened by now, often earlier than expected or before some reference point.

In this sentence, 我已经收到录用通知了, it helps express:

• By now, I have received it
• I’ve already gotten the hiring notice

Without 已经, the sentence is still possible:

• 我收到录用通知了

That still means the notice has been received, but 已经 makes the already idea more explicit.

This is a very common question.

In Mandarin, 已经 and 了 often work together in the pattern 已经...了.

They do not do exactly the same job:

• 已经 = already
• sentence-final 了 = marks a new situation, change of state, or completed development relevant now

So 我已经收到录用通知了 means something like:

• As of now, the situation has changed: I have already received the hiring notice.

The final 了 makes the sentence sound like an update or new piece of information.

If you remove 了, the sentence can still be understood, but it may feel less natural in many everyday contexts.

收到 is a very important pattern.

• 收 = to receive / to accept / to collect
• 到 here is a result complement

So:

• 收 = the action of receiving
• 收到 = to successfully receive, to have gotten

This is similar to the difference between:

• I was receiving
• I received / I got it

In this sentence, 收到录用通知 means to receive the hiring notice successfully.

That is why 收到 is more natural than plain 收 here.

Yes. That is also very natural.

Compare:

• 我已经收到录用通知了
• 我已经收到了录用通知

Both are correct and both commonly mean that the notice has been received.

A simple way to think about the difference:

• ...了 at the end often highlights the new situation now
• 收到了 often highlights the completed action of receiving

In real conversation, the difference is often small.

For a learner, both are good to know. The version in your sentence is especially natural when giving someone an update.

Because 已经 is an adverb, and in Mandarin adverbs usually come before the verb phrase.

The basic order is often:

• subject + adverb + verb + object

So here:

• 我 = subject
• 已经 = adverb
• 收到 = verb
• 录用通知 = object
• 了 = sentence-final particle

That gives:

• 我已经收到录用通知了

This word order is very normal in Mandarin.

录用通知 is a fairly formal expression.

It breaks down like this:

• 录用 = to hire, employ, or accept someone for a job
• 通知 = notice, notification

So 录用通知 means something like:

• hiring notice
• employment notice
• job offer notification

It sounds more formal than everyday casual speech.

A useful comparison:

• 录用通知 = job-related hiring notice
• 录取通知 = admission/acceptance notice, often for schools or programs

So if you are talking about a company hiring you, 录用通知 is the right kind of expression.

Because Mandarin often does not need an article like a or the.

English requires something like:

• a hiring notice
• the hiring notice

Chinese often just uses the noun directly when the meaning is clear:

• 录用通知

If you want to be more explicit, you could say:

• 一份录用通知

Here 一份 means one copy / one document / a.

So both ideas are possible:

• 收到录用通知 = received the hiring notice / a hiring notice
• 收到一份录用通知 = received a hiring notice, one notice/document

The shorter version is very normal.

Sometimes, yes.

Mandarin often drops the subject when it is clear from context. So if everyone already knows you are talking about yourself, you could say:

• 已经收到录用通知了

That sounds natural in context.

But if the sentence is standing alone, keeping 我 is safer and clearer:

• 我已经收到录用通知了

So:

• with context: subject can be omitted
• without context: keeping 我 is usually better

A natural way is:

• 我还没收到录用通知。

You can also say:

• 我还没有收到录用通知。

Important points:

• Use 没 or 没有 to negate a completed action
• Use 还 to express still or yet

So:

• 还没收到 = haven’t received yet

Learners often want to use 不, but for this kind of completed event, 没 is the normal choice.

So not:

• 我不收到录用通知

but:

• 我还没收到录用通知

It sounds fairly neutral and a bit formal because of 录用通知.

The grammar itself is not especially formal, but the vocabulary is more official or workplace-style. It sounds like something you might say:

• in a job-related conversation
• when giving an update
• in a message to family, friends, or colleagues

The final 了 can also make it feel like news or a development:

• I’ve got it now
• The situation has changed

So depending on tone of voice, it can sound calm, professional, or happy. The sentence itself does not automatically mean excitement, but it often carries that feeling in real use.
