To complete the text, we need to determine whether to use the present simple or the present continuous form of the verbs provided in brackets. Let's break it down step by step:

1. Identify the context: The present simple is used for actions that are habitual or generally true, while the present continuous is used for actions that are happening right now or around the current time.
2. Analyze the sentences:
   • In the first sentence, "I … (be) a trainee project manager," we are stating a fact about the speaker's current job. Therefore, we use the present simple: "I am a trainee project manager."
   • In the second part, "I … (love) my job," this is also a general statement about the speaker's feelings, so we again use the present simple: "I love my job."
   • Next, "I … (work) for a well-known computer manufacturer," is another fact about the speaker's employment, so we use the present simple: "I work for a well-known computer manufacturer."
   • In the sentence, "Right now, we … (develop) an advertising campaign," we are talking about an action happening at this moment, so we use the present continuous: "Right now, we are developing an advertising campaign."
   • For "We … (try) to find the best artist," this is also an ongoing action, so we use the present continuous: "We are trying to find the best artist."
   • Finally, in "this week I … (look) at samples of artists’ work every day," we are describing a current activity that is happening repeatedly this week, so we use the present continuous: "this week I am looking at samples of artists’ work every day."

Now, let's put it all together:

I am a trainee project manager and I love my job. I work for a well-known computer manufacturer, in the marketing department. Right now, we are developing an advertising campaign for our newest laptop computers. We are trying to find the best artist for our print advertisements, so this week I am looking at samples of artists’ work every day.
