Se a candidata mostrar esforço e experiência, terá uma oportunidade melhor no processo.

After se, Portuguese often uses the future subjunctive when the condition refers to a future possibility.

So:

• Se a candidata mostrar... = If the candidate shows...

Here, mostrar is not just the infinitive in meaning. It is the future subjunctive form, which happens to look exactly like the infinitive for regular -ar verbs.

Why not the others?

• mostra would sound more like a habitual or general statement in some contexts
• mostrará is not the normal form after se in this kind of conditional sentence

A very common pattern is:

• Se + future subjunctive, future indicative
• Se ela mostrar, terá...

It is a verb tense: the future subjunctive.

For many verbs, especially regular -ar verbs, the future subjunctive looks exactly like the infinitive:

• infinitive: mostrar
• future subjunctive: mostrar

So the form is the same, but the grammar role is different.

In this sentence, because it comes after se and talks about a future condition, native speakers understand it as future subjunctive.

Terá is the future indicative of ter:

• terá = will have

So:

• terá uma oportunidade melhor = will have a better opportunity

This fits the common conditional structure:

• If X happens, Y will happen
• Se X acontecer, Y acontecerá

In your sentence:

• Se a candidata mostrar esforço e experiência, terá uma oportunidade melhor no processo.

The first part gives the condition, and the second part gives the result.

Portuguese often omits subject pronouns when the subject is clear from context.

So:

• terá uma oportunidade melhor
  and
• ela terá uma oportunidade melhor

both mean the same thing here.

The subject is understood to be a candidata from the first clause.

This is very normal in Portuguese and much more common than in English.

A candidata means the candidate, so it usually refers to a specific candidate already known in the context.

• a candidata = the candidate
• uma candidata = a candidate

So the sentence sounds like it is talking about a particular candidate in a known selection process, not just any candidate in general.

If you said:

• Se uma candidata mostrar esforço e experiência...

that would feel more like if a candidate shows effort and experience..., meaning any candidate.

Because candidata is the feminine form and refers to a female candidate.

• o candidato = the male candidate
• a candidata = the female candidate

Portuguese nouns often show gender, and the article changes too:

• o
• a

The verb does not change for gender here:

• o candidato mostrar
• a candidata mostrar

The verb form stays the same.

Because esforço and experiência are being used in a general sense here, as qualities the candidate can demonstrate.

So:

• mostrar esforço e experiência = show effort and experience

This is very natural in Portuguese.

If you added articles:

• mostrar o esforço e a experiência

it would sound more like referring to specific, already identified effort and experience.

In job or evaluation contexts, Portuguese often leaves out the articles with abstract qualities like:

• mostrar interesse
• demonstrar competência
• ter experiência
• fazer esforço

Here mostrar means demonstrate or show evidence of, not necessarily physically show something.

So:

• mostrar esforço = demonstrate effort
• mostrar experiência = show that she has experience / demonstrate experience

This is very common in professional, academic, and evaluative contexts.

Similar examples:

• mostrar interesse
• mostrar comprometimento
• mostrar capacidade

So the idea is that the candidate proves these qualities through her behavior, background, or performance.

In Portuguese, adjectives often come after the noun.

So:

• uma oportunidade melhor = a better opportunity

This is the most neutral and natural order here.

You may also see:

• uma melhor oportunidade

That is possible, but it can sound a little more marked or stylistically different depending on context. For a learner, noun + adjective is the safest default in cases like this.

No is a contraction of:

• em + o = no

So:

• no processo = in the process

Here processo most likely means a selection process, application process, or recruitment process.

This kind of contraction is extremely common in Portuguese:

• em + a = na
• de + o = do
• de + a = da

So no processo is just the normal way to say in the process when the noun is masculine singular and takes o.

Yes, the sentence is natural, and it sounds a bit more formal or written because of terá.

A more conversational version might be:

• Se a candidata mostrar esforço e experiência, vai ter uma oportunidade melhor no processo.

Both are correct.

Main difference:

• terá = slightly more formal, concise, written, or polished
• vai ter = very common in everyday spoken Brazilian Portuguese

So the original sentence is perfectly good, especially in professional or written contexts.

Because the sentence begins with a conditional clause introduced by se:

• Se a candidata mostrar esforço e experiência, ...

In Portuguese, when this dependent clause comes first, a comma before the main clause is standard and recommended.

So the structure is:

• condition first
• comma
• result second

That makes the sentence easier to read and is the normal punctuation choice here.
