זה שהיא ביקשה זמן לחשוב לא אומר שהיא לא רוצה את המשרה.

Here זה does not mean a concrete this in the usual pointing sense. In this structure, זה ש... is a very common way to say the fact that... or to introduce a whole clause as one idea.

So:

זה שהיא ביקשה זמן לחשוב
= The fact that she asked for time to think

Very literally, Hebrew is using זה almost like a placeholder before the clause.

Because each ש־ introduces a new clause.

1. זה שהיא ביקשה זמן לחשוב
   = the fact that she asked for time to think

2. לא אומר שהיא לא רוצה את המשרה
   = does not mean that she does not want the position

In both cases, ש־ means that.

And שהיא is just:

• ש־ = that
• היא = she

So שהיא = that she.

Because the subject is she.

The base verb is לבקש = to ask/request.
In the past tense:

• הוא ביקש = he asked
• היא ביקשה = she asked

Since the sentence is talking about a woman, Hebrew uses the feminine singular past form ביקשה.

זמן לחשוב means time to think.

Hebrew often uses ל + infinitive where English uses to + verb:

• לחשוב = to think
• זמן לחשוב = time to think

This is very normal Hebrew syntax. You do not need an extra word between זמן and לחשוב.

Compare:

• יש לי זמן לאכול = I have time to eat
• היא ביקשה זמן לחשוב = She asked for time to think

In Hebrew, לומר basically means to say, but in expressions like this, לא אומר ש... often corresponds to English doesn’t mean that...

So:

• זה לא אומר ש... = That doesn’t mean that...

In natural English, we would usually translate it as mean, not say, even though the underlying Hebrew verb is from to say.

This is a very common expression in Hebrew.

No. Each לא negates a different part of the sentence.

• לא אומר = does not mean
• לא רוצה = does not want

So the full logic is:

The fact that she asked for time to think does not mean [that] she does not want the position.

This works the same way in English. The negatives do not cancel each other out.

Because המשרה is a definite direct object.

In Hebrew, את marks a direct object when it is definite, for example with the, a name, or a possessive.

Here:

• המשרה = the position/job
• so Hebrew uses את המשרה

Compare:

• היא רוצה משרה = She wants a position
  no את, because it is indefinite

• היא רוצה את המשרה = She wants the position
  את is required, because it is definite

Because אומר is not agreeing with she. It is connected to the whole clause introduced by זה.

The subject of אומר is essentially:

זה שהיא ביקשה זמן לחשוב
= The fact that she asked for time to think

With זה, Hebrew commonly uses masculine singular agreement by default:

• זה לא אומר...

So the masculine singular אומר is perfectly normal here, even though the person inside the clause is female.

Yes. A very literal English rendering would be:

That she asked for time to think doesn’t mean that she doesn’t want the position.

But in more natural English, people often say:

• The fact that she asked for time to think doesn’t mean she doesn’t want the position.

That is why זה ש... is often explained as the fact that...

Because the speaker wants to make the first idea the topic:

זה שהיא ביקשה זמן לחשוב
= the fact that she asked for time to think

Then the rest comments on it:

לא אומר שהיא לא רוצה את המשרה
= does not mean that she does not want the position

This structure is very natural in Hebrew when you want to focus on a specific fact or action.

A different but related structure would be:

העובדה שהיא ביקשה זמן לחשוב לא אומרת שהיא לא רוצה את המשרה.
= The fact that she asked for time to think does not mean that she does not want the position.

That version sounds a bit more explicit and formal.

Both can relate to job/work, but they are not always identical.

• משרה usually means position, post, or job opening
• עבודה can mean work in general, or a job

In this sentence, המשרה sounds a bit more like the position or the role, which fits well in hiring or employment contexts.

So:

• היא רוצה את המשרה = She wants the position
• היא רוצה את העבודה = She wants the job

Both can work in some contexts, but משרה is slightly more formal and specific.

Usually, no. In Hebrew, the ש־ is normally kept.

English can say:

• I think she’s right
• I think that she’s right

But Hebrew usually needs the equivalent of that:

• אני חושב שהיא צודקת

Here ש־ is built into שהיא.

So in your sentence, you would not normally drop it. The clause needs that connector.

It is completely natural and works well in both normal conversation and standard written Hebrew.

It is not slang, and it is not especially literary either.
A native speaker could easily say this in everyday speech:

זה שהיא ביקשה זמן לחשוב לא אומר שהיא לא רוצה את המשרה.

In speech, the intonation would help show the structure, but grammatically it is standard and very common.
