Tiene experiencia en el cargo.

Because Spanish often omits subject pronouns when they are clear from the verb form.
Tiene already tells you it is third person singular:

• he has
• she has
• you have (formal usted)

So Tiene experiencia en el cargo can mean:

• He has experience in the position
• She has experience in the position
• You have experience in the position (formal)

The context tells you which one is meant.

Tiene is the present indicative of tener for él / ella / usted.

The verb tener means to have. Its present forms are:

• yo tengo
• tú tienes
• él / ella / usted tiene
• nosotros/as tenemos
• vosotros/as tenéis
• ellos / ellas / ustedes tienen

So here, tiene = has or formal have.

In Spanish, tener experiencia is the most natural and common way to express this idea.

So Spanish says:

• tiene experiencia = has experience

You can also say things like es experimentado/a, but that usually means experienced as an adjective describing the person, and it can sound a bit more descriptive or less neutral in some contexts.

For jobs, CVs, and formal statements, tener experiencia is extremely common.

Because in Spanish, with tener + noun, the noun often appears without an article when you are speaking in a general sense.

So:

• Tiene experiencia = He/She has experience

This is like saying the person possesses experience in general, not referring to a specific, previously identified experience.

Compare:

• Tiene experiencia = has experience
• Tiene la experiencia necesaria = has the necessary experience

In the second example, la appears because the experience is now specific.

Cargo here means something like:

• position
• post
• role
• office

In Spain, cargo often sounds a bit formal and can suggest a position of responsibility, authority, or official status.

Depending on context, it may overlap with:

• puesto = position/post
• empleo = job/employment
• función = function/role

So en el cargo is often understood as in that position / in that post.

Both can mean position, but there is often a nuance:

• puesto is a very common general word for a job position
• cargo can sound more formal, and often suggests a post with duties, rank, or responsibility

For example:

• Tiene experiencia en el puesto = very natural, general
• Tiene experiencia en el cargo = also natural, but a bit more formal or institutional

In business, administration, and official contexts, cargo is especially common.

Because en el cargo means in the position / in the role — it refers to experience within that job or post.

• experiencia en el cargo = experience in the role/position

If you said para el cargo, that would sound more like:

• for the position
• suitable or relevant for the position

So the meanings are different:

• Tiene experiencia en el cargo = has experience doing that job
• Tiene experiencia para el cargo = less natural here; it would suggest experience relevant to qualifying for the post

Because in Spanish, only two preposition + article combinations contract:

• a + el = al
• de + el = del

But:

• en + el stays en el
• con + el stays con el

So en el cargo is correct. There is no contraction here.

Yes. Because the subject pronoun is omitted, this sentence can refer to:

• he
• she
• you (formal usted)

That is normal in Spanish.

If you want to make it explicit, you can say:

• Él tiene experiencia en el cargo
• Ella tiene experiencia en el cargo
• Usted tiene experiencia en el cargo

Usually, though, Spanish leaves the pronoun out unless it is needed for emphasis or clarity.

Yes. Experiencia is often used as an uncountable/general noun in this kind of sentence, much like English experience.

So:

• Tiene experiencia = has experience

You can use the plural experiencias, but that usually means individual experiences or separate events:

• Ha tenido muchas experiencias interesantes = He/She has had many interesting experiences

In job-related Spanish, the singular experiencia is the normal choice.

Very easily:

• ¿Tiene experiencia en el cargo? = Does he/she/you have experience in the position?
• No tiene experiencia en el cargo. = He/She/You do not have experience in the position.

In Spanish, you usually do not need an extra verb like do/does to make questions or negatives.

So:

• statement: Tiene experiencia en el cargo.
• question: ¿Tiene experiencia en el cargo?
• negative: No tiene experiencia en el cargo.

It depends on context.

En el cargo often suggests experience in that specific position/post, but in real use it can sometimes also mean experience serving in that kind of role.

For more precision, Spanish often adds something:

• Tiene experiencia en este cargo = in this position
• Tiene experiencia en un cargo similar = in a similar position
• Tiene experiencia como director = has experience as a director

So the basic sentence is slightly broad, and context tells you how specific it is.
