Prima di inviare la candidatura, controllo il curriculum con attenzione.

Because in Italian, prima di means before when it is followed by a verb.

• prima di + infinitive = before doing something
• prima di inviare = before sending

So:

• Prima di partire = Before leaving
• Prima di mangiare = Before eating

If prima is not followed by a verb, it can stand alone in other structures, but here di is necessary.

It is in the infinitive because it comes after di in the structure prima di + infinitive.

This is very common in Italian:

• prima di uscire = before going out
• dopo aver mangiato = after eating
• senza parlare = without speaking

So inviare stays in its base verb form, meaning to send.

La candidatura means the application or the candidacy, depending on context.

In this sentence, it most naturally means a job application or application submission.

Italian often uses:

• candidatura = application/candidacy
• candidarsi = to apply / to put oneself forward

In job-related Italian, you may also hear:

• mandare la candidatura
• inviare la candidatura
• presentare la candidatura

All are natural in the right context.

Italian often drops the subject pronoun when it is clear from the verb ending.

• controllo already means I check
• the -o ending shows first person singular

So:

• controllo = I check
• io controllo = I check

Adding io is possible, but it usually adds emphasis or contrast:

• Io controllo il curriculum, tu scrivi la lettera.
  = I check the résumé, you write the letter.

Without emphasis, Italian usually leaves the pronoun out.

Italian often uses the present tense to describe habitual actions, routines, or general truths.

Here, controllo can mean:

• I check the résumé before sending the application or
• Before sending the application, I check the résumé

It sounds like a normal habit or step in a process.

This is similar to English when you describe a routine:

• Before I leave, I lock the door.

So the present tense works perfectly here.

Yes. Il curriculum is very common in Italian, especially in the phrase:

• curriculum vitae
• often shortened to simply curriculum

In everyday Italian, people commonly say:

• mandare il curriculum
• aggiornare il curriculum
• controllare il curriculum

So il curriculum here means the résumé/CV.

Because in modern Italian, curriculum is treated as a singular masculine noun.

So:

• il curriculum = the résumé
• i curriculum is sometimes used, but many speakers prefer other solutions in practice, such as repeating the noun differently depending on style

For a learner, the important thing is:

• singular: il curriculum
• it is masculine

Even though the word comes from Latin, Italian grammar treats it according to modern usage, not Latin grammar.

Con attenzione means carefully or with attention.

Italian often uses:

• con + noun instead of a single adverb.

So these are similar:

• controllo il curriculum con attenzione
• controllo attentamente il curriculum

Both are correct.

There can be a slight stylistic difference:

• con attenzione can sound a bit more deliberate or formal
• attentamente is a straightforward adverb

Both are natural.

Yes. That word order is also correct.

Both are natural:

• controllo il curriculum con attenzione
• controllo con attenzione il curriculum

The first one may feel slightly more neutral. The second can place a little more focus on how you check it.

Italian word order is often flexible, especially with adverbial phrases like con attenzione.

The comma separates the introductory phrase from the main clause.

• Prima di inviare la candidatura = introductory time phrase
• controllo il curriculum con attenzione = main clause

This is similar to English:

• Before sending the application, I check the résumé carefully.

The comma helps readability. In short sentences, punctuation can sometimes vary, but here the comma is very natural.

Yes. Mandare and inviare can both mean to send.

However:

• inviare often sounds a bit more formal or professional
• mandare is more everyday and general

Since the sentence is about a job application, inviare la candidatura sounds especially appropriate.

So both are possible, but inviare fits the register very well.

You could use other expressions depending on what exactly you mean.

Common alternatives include:

• la domanda = the application
• la domanda di lavoro = the job application
• la candidatura = the candidacy/application
• la richiesta = the request, in other contexts

For job searching, candidatura is very common and natural. It often suggests applying for a position in a fairly professional context.

Yes, but it changes the meaning slightly.

• inviare la candidatura = send the application
• inviare il curriculum = send the résumé/CV

Sometimes these actions happen together, but they are not exactly the same thing.

If you want to say that you check the résumé before sending the résumé itself, then:

• Prima di inviare il curriculum, controllo il curriculum con attenzione.

That is grammatically correct, though a bit repetitive.

If the idea is that you review your résumé before submitting your whole application, the original sentence is more precise.

Yes, it is natural and correct.

It sounds like standard, neutral Italian, especially in a professional or practical context. The vocabulary and structure are very normal:

• Prima di + infinitive
• omitted subject pronoun
• controllare il curriculum
• con attenzione

A slightly different but equally natural version could be:

• Prima di inviare la candidatura, controllo attentamente il curriculum.

But the original sentence is already good Italian.
