yàobúshì péngyou bāng wǒ kàn jiǎnlì, wǒ búhuì shōudào lùyòngtōngzhī.

要不是 means if it weren’t for... / but for.... It introduces a condition that prevented a different outcome.

In this sentence, it shows a counterfactual idea:
the speaker did receive the job offer, and they are saying that without their friend’s help, that would not have happened.

So 要不是朋友帮我看简历，我不会收到录用通知 means something like:
If it weren’t for my friend helping me look over my résumé, I wouldn’t have received the offer.

Both can be translated as if it were not for, but 要不是 often sounds:

• more natural in everyday speech
• more emotional or emphatic
• more strongly connected to a result that actually happened

如果不是 is more neutral and literal.

So in this sentence, 要不是 fits well because the speaker is reflecting on a real outcome and emphasizing how important the friend’s help was.

That is a very common question. Yes, Chinese often uses 就 in this kind of pattern:

• 要不是朋友帮我看简历，我就不会收到录用通知。

This is very natural.

But 就 can also be omitted, especially when the meaning is already clear. Without 就, the sentence is still completely grammatical. The version without 就 sounds a little more concise.

So both are fine:

• 要不是朋友帮我看简历，我不会收到录用通知。
• 要不是朋友帮我看简历，我就不会收到录用通知。

Because the speaker is talking about a hypothetical result, not describing what actually happened.

• 不会收到 = would not receive
• 没收到 = did not receive

In this sentence, the speaker actually did receive the hiring notice. They are saying that in the imagined situation where the friend did not help, they would not have received it.

So 不会收到 is the correct choice for this counterfactual meaning.

Here 看 does not just mean physically look at. It means something more like:

• read over
• check
• review
• look through

So 朋友帮我看简历 means the friend helped by reviewing the speaker’s résumé.

This is a very common use of 看 in Chinese. Depending on context, 看 can mean:

• look at
• read
• watch
• check
• examine

Here, check/review is the best fit.

This is a very common Chinese structure:

• 帮 + person + verb phrase

So:

• 帮我看简历 = help me review the résumé

Breaking it down:

• 帮 = help
• 我 = me
• 看简历 = review the résumé

The friend is the subject of the clause:

• 朋友帮我看简历 = my friend helped me review my résumé

Chinese often puts these elements together very directly, without extra words like to.

Chinese often leaves out possessive words when the meaning is obvious from context.

Here, 帮我看简历 naturally implies help me look at my résumé, not someone else’s. Because that is already clear, Chinese does not need to say 我的简历.

You could say:

• 朋友帮我看我的简历

But it sounds less natural unless you want to emphasize that it was specifically my résumé.

So the shorter version is preferred here.

Chinese nouns often appear without articles such as a, an, or the, because Chinese does not have articles in the same way English does.

So 朋友 can mean:

• a friend
• my friend
• friends

The exact meaning depends on context.

In this sentence, English would usually say my friend, because that sounds most natural. But in Chinese, just 朋友 is enough when the relationship is clear from the situation.

If the speaker wanted to be more explicit, they could say:

• 要不是我的朋友帮我看简历...

That is also correct.

录用通知 is a formal phrase meaning something like:

• notice of hiring
• hiring notice
• job offer notification

In natural English, it is often translated simply as job offer or offer letter, depending on context.

Breaking it down:

• 录用 = hire / employ / accept for a position
• 通知 = notice / notification

So the phrase refers to the message or document telling someone they have been accepted for the job.

收到 means to receive something that is sent, given, or delivered to you.

That fits well with 录用通知, because a notice or letter is something you receive.

• 收到录用通知 = receive a hiring notice

得到 means to obtain / get, and it is more general. It can sometimes work with abstract things, but with 通知, 收到 is the more natural choice.

So in this sentence, 收到 is the best word.

This is because of tone sandhi.

Normally, 不 is fourth tone: bù.
But when 不 comes before another fourth-tone syllable, it changes to second tone: bú.

Here:

• 会 is fourth tone: huì
• so 不 + 会 becomes búhuì

This is a standard pronunciation rule in Mandarin.

Yes, it can.

For example:

• 要不是朋友帮我看简历，我就不会收到录用通知了。

Adding 了 can make the sentence sound a bit more like:

• a realization
• a conclusion
• emphasis on the changed outcome

Without 了, the sentence is still perfectly natural and complete.
With 了, the speaker may sound slightly more reflective or emphatic.

Yes. Chinese does not mark tense the same way English does.

The time reference is understood from:

• the overall situation
• the logic of the sentence
• the result 收到录用通知

This sentence clearly refers to a completed real-life situation:
the friend helped, and the speaker received the hiring notice.

Chinese often relies on context instead of changing verb forms for past, present, or future.

Yes, but it changes the meaning slightly.

• 帮我看简历 = help me review/check my résumé
• 帮我修改简历 = help me revise/edit my résumé

So:

• 看 focuses on looking over it
• 修改 focuses on making changes to improve it

If the friend actually edited the résumé, 修改 may be better.
If they mainly read it and gave feedback, 看 is very natural.

The sentence follows this pattern:

• 要不是 + reason/condition, (就) + would not/would have...

So the structure is:

• 要不是朋友帮我看简历，
• 我不会收到录用通知。

This is a very useful pattern for expressing:

• if it hadn’t been for...
• otherwise, ... would not have happened

You can use it in many situations, for example:

• 要不是你提醒我，我就迟到了。
  If you hadn’t reminded me, I would have been late.

• 要不是天气好，我们不会去爬山。
  If it weren’t for the good weather, we wouldn’t go hiking.

It is a common way to express gratitude, relief, or reflection on what might have happened differently.
