Considering "select" as an adjective. Could we say "I am select for the job" and "I got/became select for the job"
No, one is either select or not select; a person isn't generally select "for" something. (Also, the adject "select" is usually used attributively, not predicatively, although the latter isn't necessarily wrong.) It would be better to say:
I have been selected for the job.
I was selected for the job.
I got selected for the job.
I am being selected for the job.
(You didn't ask specifically about the verb, but note that some verb forms work better than others, depending on the intended meaning.)
I hazard a guess that this is some kind of homework: write a sentence using "select" as an adjective.
So, English isn't as simple as it looks. The past tense of "select" is "selected", so the sentences you wrote would have to look like this to be corect:
"I was selected for the job" and "I got selected for the job"
("became selected" is not something a NS would say, however correct it might look.)
Now, if you want to use "select" as an adjective, try this sort of thing:
- As one of the select few he received a job.
- The office was manned by a select collection of volunteers.
- A basket of select brands of chocolates
But I must say, it's hard to find examples which don't look strange.
The only case that I am aware of in which the adjective select is commonly used is in the phrase a select few, such as in "The luxury of traveling by private jet is only available to a select few." Select basically modifies few then and means "of only the best type or highest quality, and usually small in size or amount" .
If you're trying to say that you're (one of) the best candidate(s) for the job, I'd say something like
- I'm the ideal candidate for the job
- I'm well-suited for the job
- I'm uniquely qualified for the job
