Răspunzând recrutorului, candidatul pare încrezător.

Yes. Răspunzând is the gerund of a răspunde (to answer / to respond).

In this sentence, it works a lot like English answering in a phrase such as:

• Answering the recruiter, the candidate seems confident
• more naturally in English: While answering the recruiter, the candidate seems confident

So răspunzând often gives the idea of while doing X or sometimes by doing X.

Because a răspunde usually takes an indirect object in Romanian, so the person being answered is put in the dative case.

• recrutorul = the recruiter (subject/direct form)
• recrutorului = to the recruiter (dative form)

So:

• a răspunde cuiva = to answer someone / respond to someone
• răspunzând recrutorului = answering the recruiter / responding to the recruiter

Even though English says answer someone without to, Romanian normally uses the structure equivalent to respond to someone.

Romanian usually puts the definite article at the end of the noun instead of using a separate word like English the.

So:

• candidat = candidate
• candidatul = the candidate

That ending -ul is the masculine singular definite article.

Pare is the 3rd person singular present form of a părea, meaning to seem / to appear.

So:

• pare = seems
• candidatul pare încrezător = the candidate seems confident

It behaves like a linking verb, similar to English seem.

Because încrezător is not a noun here; it is an adjective used after the verb pare.

In sentences with linking verbs like a fi (to be) or a părea (to seem), Romanian often uses an adjective as a subject complement:

• Candidatul este încrezător. = The candidate is confident.
• Candidatul pare încrezător. = The candidate seems confident.

It does not take the definite article here.

Also, it agrees with candidatul:

• masculine singular: încrezător
• feminine singular: încrezătoare

For example:

• Candidata pare încrezătoare.

The natural interpretation is that the candidate is doing the answering.

In Romanian, a gerund phrase like răspunzând recrutorului usually refers to the same subject as the main clause, unless context strongly suggests otherwise.

So this sentence is understood as:

• While answering the recruiter, the candidate seems confident.

It would be odd or unclear to interpret it as the recruiter answering someone.

Yes, in normal writing the comma is appropriate.

The phrase Răspunzând recrutorului is an introductory gerund phrase, and Romanian commonly separates this kind of phrase with a comma:

• Răspunzând recrutorului, candidatul pare încrezător.

This is similar to English writing:

• Answering the recruiter, the candidate seems confident.

The comma helps show that the first part is an additional circumstance, not the main clause itself.

Yes. Romanian often allows a more explicit clause instead of the gerund.

For example:

• În timp ce îi răspunde recrutorului, candidatul pare încrezător.
  = While he is answering the recruiter, the candidate seems confident.

This version is more explicit because it uses a full clause with a finite verb.
The original sentence is more compact and slightly more formal or written in style.

Because Romanian does not need to double the indirect object here.

You can say:

• răspunzând recrutorului

and that is perfectly normal.

Sometimes Romanian uses clitic doubling, especially with certain objects or for emphasis, but with this structure it is not required. A fuller version like răspunzându-i recrutorului can exist in some contexts, but the sentence as given is completely natural without îi.

In this sentence, it is most naturally while answering.

The context is descriptive: it tells us what the candidate seems like during the action.

So the sense is:

• While answering the recruiter, the candidate seems confident.

A by answering reading is possible with Romanian gerunds in some sentences, but here that would sound less natural in English because seems confident by answering is not the intended idea.

Yes, Romanian word order is fairly flexible, though the original is very natural.

Original:

• Răspunzând recrutorului, candidatul pare încrezător.

Possible alternative:

• Candidatul pare încrezător răspunzând recrutorului.

This still makes sense, but the original version is better because the gerund phrase works smoothly as an introductory element. It sounds more polished and is easier to process.

Yes, mainly these points:

1. Romanian uses a gerund (răspunzând) where English often prefers a full clause like while answering.
2. a răspunde takes the person answered in the dative:
   • recrutorului = to the recruiter
3. The definite article is attached to the noun:
   • candidatul = the candidate
4. pare is a linking verb:
   • pare încrezător = seems confident
5. The subject of the gerund phrase is normally the same as the main subject:
   • the candidate is the one answering.
