Diary #1: aA little about my work

I have been using this platform to practice my academic writing for the IELTS, h. However, today I want to talk about myself.

I got recently got hired by an American firm who works with American veterans.

I have heard stories of Latinos who work with American customers, and sometimes they are rude to them just because they have an accent, but t. To be fair, I myself have not experienced anything like that so far.

Also, according to my boss, I will not have to deal with a lot of calls in my daily life, but. I am still afraid, though. haha.

I gotwas inspired by some other users who regularly write about personal topics.

Got works too but I think was would be more commonly used in this case

In English adverbs like recently often go between the subject and verb, but I understand that in other languages you don’t want to break the two up. If you still wanted to have it as a subject+verb+adverb kind of format then something like “I was recently hired…” might be a good choice.
Since “an American firm” refers to a singular subject, it would be works with the S.
“Who” might also work in this sentence but personally I tend to prefer using “that” unless referring to a specific person

Although it has been an amazing job opportunity, sometimes I feel that my English is not good enough.

Could also replace feel with think but in relation to that part both work

I am scared that I will have to answer the phone and the customers will realize that I have a Latino accent.

I would add in “will” since you’re speaking about the future (as in you’re not saying that you have to answer the phone right now, so you would use something like “will” or “am going to” to indicate future tense)

For formal writing, titles are usually capitalized.

But if it's informal, it is your choice!

I am scared thatwhen I have to answer the phone and, the customers will realize that I have a Latino accent.

It sounds a little more natural to say "when I answer the phone" and to get rid of the and

This sounds natural for speech! In writing, we would break it into two sentences because there are multiple ideas.

I am sorry people are having this experience, and hope it doesn't happen to you.

Also, according to my boss, I will not have to deal with a lot of calls in my daily life, but I am still afraid haha.

Your sentence is ok, too. I just cleaned it up a bit.

Since the rest of this post is written in a neutral style, not especially casual, I think it's less jarring without the "haha" inflection. "haha" is fine in casual writing to friends.

Because you are talking about a thing not a person, you can say "that" instead of "who". Also, because "the firm" is a singular entity, you should use the verb "works" rather than "work"

Although it has been an amazing job opportunity, sometimes I feel that my English is not enoughsufficient.

Although you aren't technically wrong, it's a little more common to say "not sufficient" or "not *good* enough" in this context ~ But your English definitely seems sufficient!

I am scared that I'll have to answer the phone and the customers will realize that I have a Latino accent.

Since you are talking about a hypothetical future situation, you can say "I'll" instead of "I" so that the tense is consistent throughout the sentence.
