De verdad, no quiero mentir en la entrevista.

Yes—de verdad often means really, truly, or honestly depending on context.

In this sentence, De verdad adds emphasis, like:

• Honestly, I don’t want to lie in the interview.
• Really, I don’t want to lie in the interview.
• I truly don’t want to lie in the interview.

It makes the speaker sound sincere.

In Spain, de verdad is very common in everyday speech.

Because Spanish usually makes a sentence negative by putting no directly before the conjugated verb.

So:

• quiero = I want
• no quiero = I don’t want

That is the normal Spanish pattern:

• No tengo tiempo = I don’t have time
• No puedo ir = I can’t go

Here, no negates quiero, so the meaning is I do not want.

Because after querer (to want), Spanish normally uses an infinitive.

So the pattern is:

• querer + infinitive

Examples:

• Quiero salir = I want to leave
• Quiero comer = I want to eat
• No quiero mentir = I don’t want to lie

This is different from English, where you often use to:

• I want to lie
• I want to eat

In Spanish, there is no separate word like to before the second verb in this structure.

Because after quiero, Spanish needs the infinitive, and mentir is the infinitive form meaning to lie.

Compare:

• mentir = to lie (infinitive)
• miento = I lie
• mentí = I lied

So:

• Quiero mentir = I want to lie
• No quiero mentir = I don’t want to lie

If you said no quiero miento, that would be ungrammatical.

No. Mentir is a stem-changing verb.

In many present-tense forms, the e changes to ie:

• yo miento
• tú mientes
• él/ella miente
• nosotros mentimos
• vosotros mentís
• ellos/ellas mienten

But in this sentence, it appears as the infinitive mentir, so there is no stem change visible there.

Here, en la entrevista can often be understood in English as either in the interview or at the interview, depending on style.

Spanish en covers a range that English often splits into in, on, or at.

So:

• en la entrevista = in the interview / at the interview

In natural English, at the interview may sound slightly more common if you mean the event itself, while in the interview can sound natural if you mean what is said during it.

Since the Spanish meaning is already clear, the important point is that en is the normal preposition here.

Spanish uses definite articles (el, la, los, las) more often than English does.

So even when English might say:

• in an interview
• in the interview
• during the interview

Spanish may naturally say:

• en la entrevista

Depending on context, la entrevista usually means the interview, referring to a specific interview already understood by the speakers.

If you wanted to say an interview, you would normally say una entrevista.

Because Spanish often leaves out subject pronouns when the verb already shows who the subject is.

• quiero already means I want
• so yo is not necessary

That is very common in Spanish:

• Tengo hambre = I’m hungry
• No puedo ir = I can’t go
• Quiero hablar contigo = I want to speak with you

You could say yo no quiero mentir en la entrevista, but adding yo gives extra emphasis, something like:

• I don’t want to lie in the interview

Without yo, the sentence sounds more neutral and natural.

The comma shows that De verdad is being used as an introductory expression.

It separates the emphasis from the main statement:

• De verdad, no quiero mentir en la entrevista.

This is similar to English punctuation in sentences like:

• Honestly, I don’t want to lie.
• Really, I don’t want to do that.

Without the comma, people would still understand it, especially in informal writing, but the comma makes the structure clearer.

Yes. La verdad is also very common and can mean to be honest, honestly, or the truth is.

So these are both natural:

• De verdad, no quiero mentir en la entrevista.
• La verdad, no quiero mentir en la entrevista.

They are close, but the feeling can be slightly different:

• de verdad often emphasizes sincerity: really / truly
• la verdad can sound more like: honestly / the truth is

Both are common in Spain.

Not necessarily by itself. Entrevista just means interview.

It could be:

• a job interview
• a media interview
• an academic interview
• another kind of interview

The context would tell you which kind is meant. Many learners may assume job interview, and that is a very plausible reading, but the word itself is broader.

Yes, but the original order is the most natural for a neutral statement.

Standard version:

• De verdad, no quiero mentir en la entrevista.

Possible variations include:

• No quiero mentir en la entrevista, de verdad.
• De verdad no quiero mentir en la entrevista.
• Yo no quiero mentir en la entrevista.

These can slightly change the emphasis:

• putting de verdad at the end can sound like an afterthought or extra reassurance
• adding yo emphasizes the speaker
• removing the comma can make the sentence feel a bit more direct or spoken

But the original sentence is perfectly natural.

The original sentence is neutral and natural.

A slightly more formal version might be:

• Sinceramente, no quiero mentir en la entrevista.
• La verdad es que no quiero mentir en la entrevista.

A more casual spoken version might be:

• De verdad, no quiero mentir en la entrevista.
• En serio, no quiero mentir en la entrevista.

Note that en serio often means seriously, and in some contexts it can sound a bit more conversational than de verdad.

So the given sentence is already a good everyday Spanish sentence for Spain.
