Заповніть заявку, прикріпіть резюме і подайте документ.

Because they are in the imperative form, used for giving instructions or commands.

In this sentence, the forms are specifically the plural / polite imperative:

• заповніть = fill out
• прикріпіть = attach
• подайте = submit

In Ukrainian, the same form is used when speaking:

• to more than one person, or
• to one person politely (like formal you)

So this sentence sounds like a standard instruction you might see on a website, form, or official notice.

In Ukrainian, the subject is often omitted when it is clear from the verb ending.

So Заповніть заявку already means Fill out the application / Please fill out the application.
You do not need to say Ви заповніть... unless you want extra emphasis, contrast, or a special tone.

This is very normal in instructions:

• Натисніть кнопку. = Press the button.
• Виберіть мову. = Choose a language.

They are both direct objects, so they are in the accusative case, but different noun types change differently.

заявку

The dictionary form is заявка.
It is a feminine noun ending in -а, and in the accusative singular it changes:

• заявка → заявку

документ

The dictionary form is документ.
It is a masculine inanimate noun, and for many such nouns, the accusative singular looks the same as the nominative:

• документ → документ

So both are accusative, but the forms happen to look different because they belong to different noun patterns.

Резюме is an indeclinable noun in Ukrainian. That means it usually keeps the same form in all cases.

So:

• прикріпіть резюме = attach the résumé
• немає резюме = there is no résumé
• з резюме = with the résumé

Many borrowed words in Ukrainian behave this way, especially ones ending in -е, -і, -ю, or similar unstressed vowels.

These verbs are perfective, which is very common in step-by-step instructions.

• заповнити = to fill out completely
• прикріпити = to attach
• подати = to submit/file

In an instruction like this, the speaker usually wants the action to be seen as a completed task. That is why perfective verbs fit well.

Compare the idea:

• Заповнюйте could sound more like be filling out / fill out repeatedly / do the process
• Заповніть sounds like complete this action

So the sentence gives clear one-time actions to complete.

Both can often be translated as fill out the form/application, but they are not always identical.

• заявка usually means an application, request, or submission
• анкета usually means a questionnaire or form with personal details

Depending on context:

• заповніть заявку = fill out the application/request
• заповніть анкету = fill out the questionnaire/form

In real-world usage, the exact English equivalent depends on what kind of document is being completed.

Because the sentence is a list of separate imperative actions:

1. Заповніть заявку
2. прикріпіть резюме
3. і подайте документ

Ukrainian often separates items in a sequence with commas, just like English:

• Fill out the application, attach the résumé, and submit the document.

The final і means and.

Usually yes. Here і simply joins the last action in the list:

• ..., прикріпіть резюме і подайте документ.
• ..., attach the résumé and submit the document.

Ukrainian also has й and та, which can sometimes also mean and:

• і
• й
• та

The choice can depend on style, rhythm, or surrounding sounds. In this sentence, і is the most straightforward neutral choice.

In this context, подайте документ most naturally means submit the document or file the document.

The verb подати has a broad range of meanings depending on context, including:

• submit
• hand in
• file
• present
• sometimes even serve (for example, food)

But in administrative or online-form language, подати документ is a very standard way to say submit a document.

It is neutral to formal, which is exactly what you would expect in instructions on a website, in an office, or in official communication.

Reasons it sounds formal/standard:

• the polite/plural imperative forms (-іть, -айте)
• the administrative vocabulary (заявка, резюме, документ)
• the concise instruction style

It does not sound rude. It is the normal style for public-facing instructions.

If you were speaking casually to one person, the imperative forms would usually be singular:

• Заповни заявку, прикріпи резюме і подай документ.

So the contrast is:

• Заповніть, прикріпіть, подайте = plural / polite
• Заповни, прикріпи, подай = singular informal

The original sentence is the version you are much more likely to see in official instructions.
