Hi Lorena,

few remarks for you

whenever you're talking about jobs, you need to use "a/an" (write few other sentences for your relatives/friends)

be interested in something; be interested in doing something

whose is used when you're talking about possession/having/owning of people/or owned animals (exp: my friend whose hair is blue wants to meet you. If you decompose this sentence: my friend has blue hair (here we're talking about possession)

would like to + verb basic form (please write few other sentences with this form. this is the form of politeness so whenever you need to make a polite request/proposal you can use this form)

keep up the good work :)
