L'empresa explica les condicions laborals a l'entrevista de feina.

Because la becomes l' before a vowel sound in Catalan.

• la empresa → l'empresa
• This is called elision
• It works like:
  • l'escola
  • l'aigua
  • l'oficina

So L'empresa simply means the company.

Explica is the 3rd person singular present tense of explicar (to explain).

So:

• jo explico = I explain
• tu expliques = you explain
• ell/ella explica = he/she explains

Since l'empresa is singular, the verb must also be singular:

• L'empresa explica = The company explains

Because condicions is a feminine plural noun, so it takes the feminine plural article les.

Breakdown:

• la condició = the condition
• les condicions = the conditions

And laborals agrees with condicions in number:

• condicions laborals = working conditions / labor conditions

So everything matches:

• les = feminine plural article
• condicions = feminine plural noun
• laborals = plural adjective

In Catalan, adjectives often come after the noun, especially when they are classifying or descriptive in a straightforward way.

So:

• condicions laborals = working conditions
• literally: conditions laboral/work-related

This is normal word order in Catalan. English often puts adjectives before the noun, but Catalan usually puts many of them after it.

A l'entrevista means at the interview or in the interview, depending on context.

It is made from:

• a = at / to / in
• l' = the
• entrevista = interview

So:

• a + l'entrevista = at the interview

In this sentence, it tells you the setting or moment when the company explains the working conditions.

Catalan commonly uses a for location or event contexts where English might say at or sometimes in.

So a l'entrevista de feina is a very natural way to say:

• at the job interview

You may also see en in some contexts in Catalan, but with events or places like this, a is extremely common and natural.

For the same reason as in l'empresa: the article loses its vowel before a word beginning with a vowel.

• la entrevista → l'entrevista

This is standard Catalan spelling.

So:

• la + entrevista becomes l'entrevista
• a + l'entrevista stays a l'entrevista

De feina means of work or more naturally job-related.

So:

• entrevista = interview
• entrevista de feina = job interview

This is a very common Catalan way to build noun phrases: noun + de + noun.

Other examples:

• roba de feina = work clothes
• horari de feina = work schedule

Yes, although they often overlap.

• feina often means job, work, or task, and is very common in everyday speech
• treball can mean work in a broader sense, and also piece of work, assignment, or labor

In entrevista de feina, feina sounds very natural for job interview.

You might also hear entrevista de treball, but entrevista de feina is especially common in everyday Catalan.

No. Here it is best understood as a place/time/event expression, not an indirect object.

The direct object is:

• les condicions laborals = what the company explains

And a l'entrevista de feina tells you where/when this happens:

• at the job interview

If there were an indirect object, it would usually be the person receiving the explanation, for example:

• L'empresa explica les condicions laborals als candidats
  = The company explains the working conditions to the candidates

Here, als candidats would be the indirect object.

Yes. Catalan word order is flexible, although the original sentence is completely normal.

You could also say:

• A l'entrevista de feina, l'empresa explica les condicions laborals.

This puts more emphasis on the setting: at the job interview.

But the original order is neutral and natural:

• L'empresa explica les condicions laborals a l'entrevista de feina.

Yes. Depending on context, Catalan speakers might also say:

• condicions de treball

Both can refer to working conditions.

Very roughly:

• condicions laborals sounds a bit more formal or institutional
• condicions de treball is also common and very clear

In your sentence, condicions laborals fits well, especially in a professional or HR-related context.

Yes, very often. Catalan uses definite articles a lot, as other Romance languages do.

So it is natural to say:

• L'empresa = the company
• les condicions laborals = the working conditions
• l'entrevista de feina = the job interview

In English, articles are sometimes omitted in places where Catalan keeps them, so this is something learners often need to get used to.
