I would like to talk about the use of the present perfect talking about life experience/ achievements.
In an interview, I would like to tell the interviewer that I have a life experience as winning a (one) prize in a contest for developers.
I think that present perfect is proper because it implies that in the future I can take part in other contests, and winning a contest is also considered as my life experience.
Can you introduce yourself?:
- I worked with X company in 2020, Y company in 2022…. In addition, I have won/won a prize in a contest for developers nationwide. This prize is so meaningful for my career.
**Adding to clarify my question :
As advised in the comments, I understand that with 1 prize so far, I can use either tense. What if I have 2 prizes so far?
I have other 2 similar situations:
*Situation 1:
In 2010, I visited Thailand.
In 2016, I visited Thailand.
I would say to my friend:
- I have been to Thailand 2 times. It is a beautiful country. I wish I could visit one more time.
*Situation 2:
In 2010, I won a prize in a contest for developer nationwide.
In 2016, I won another prize in another contest for developer nationwide.
In an interview, I would say:
3.About my achievements, I won/ have won 2 prizes. These prizes are important to my career.
Natives told me that, I can use either "I won/I have won" in this situation.
I don't understand that why I can't use "I was" the same way as "I won" for the Thailand example:
I was in Thailand 2 times. It is a beautiful country. I wish I could visit it one more time.
