Tôi nhận việc sau cuộc phỏng vấn.

In this sentence, nhận việc means something like take a job, accept a job, or sometimes start a job/position.

• nhận = receive, accept, take
• việc = work, job

So literally, it is something like accept work or take the job.

Depending on context, English may translate it differently, but nhận việc usually does not focus on the employer choosing you. It focuses more on you taking the job.

Not exactly.

For I got the job in the sense of I was hired, Vietnamese more often uses:

• Tôi được nhận vào làm.
• Tôi được tuyển.

Tôi nhận việc more naturally suggests:

• I accepted the job
• I took the position
• I started the job

So if the intended meaning is specifically I was hired after the interview, this sentence may sound slightly different from that.

Vietnamese often does not mark tense the way English does.

The sentence Tôi nhận việc sau cuộc phỏng vấn can be understood from context. The phrase sau cuộc phỏng vấn already gives a time sequence, so a past interpretation is easy.

If you want to make the past clearer, you can add đã:

• Tôi đã nhận việc sau cuộc phỏng vấn.

That makes the past meaning more explicit, but leaving it out is very normal in Vietnamese.

Cuộc is a classifier-like word often used for events, activities, or occurrences.

So:

• phỏng vấn = interview / to interview
• cuộc phỏng vấn = the interview event, an interview

Other similar examples:

• cuộc họp = meeting
• cuộc thi = competition
• cuộc trò chuyện = conversation

In this sentence, cuộc helps make phỏng vấn clearly into a noun phrase: the interview / an interview.

Usually, sau cuộc phỏng vấn sounds more complete and natural.

Sau phỏng vấn may be understood in casual or shortened speech, but it is less standard. Using cuộc makes it clearer that you mean the interview event.

A very natural alternative is:

• sau khi phỏng vấn

But this structure is a little different grammatically.

The difference is:

• sau + noun phrase
• sau khi + clause/verb phrase

So:

• sau cuộc phỏng vấn = after the interview
• sau khi phỏng vấn = after interviewing / after the interview happened

In your sentence, cuộc phỏng vấn is a noun phrase, so sau cuộc phỏng vấn is the correct pattern.

If you use sau khi, what comes after it is usually a verb phrase, for example:

• Sau khi phỏng vấn, tôi nhận việc.
• Sau khi phỏng vấn xong, tôi nhận việc.

Vietnamese often places time expressions either at the beginning or end of the sentence.

So both of these are natural:

• Tôi nhận việc sau cuộc phỏng vấn.
• Sau cuộc phỏng vấn, tôi nhận việc.

The meaning is basically the same. The second version gives a little more emphasis to the time phrase.

Vietnamese does not use articles like a, an, and the in the same way English does.

So cuộc phỏng vấn can mean:

• the interview
• an interview

The exact meaning depends on context.

If you want to be more specific, you can add words such as:

• một cuộc phỏng vấn = an interview
• cuộc phỏng vấn đó = that interview
• cuộc phỏng vấn này = this interview

Tôi is a safe, neutral pronoun and is very common in textbooks. It works well in many situations, especially when you want to sound polite and neutral.

However, in real life, Vietnamese pronouns depend a lot on age, relationship, and social context. Depending on who is speaking, someone might say:

• em
• anh
• chị
• mình

So tôi is correct, but it is not the only possible subject pronoun.

It is understandable and can be natural, but the best version depends on the exact meaning you want.

If you mean I accepted the job after the interview, your sentence works well:

• Tôi nhận việc sau cuộc phỏng vấn.

If you mean I was hired after the interview, many native speakers would prefer something like:

• Tôi được nhận vào làm sau cuộc phỏng vấn.
• Sau cuộc phỏng vấn, tôi được tuyển.

So the sentence is fine, but nhận việc has a specific nuance, and that nuance may not always match English got the job exactly.
