When I am asked such a question "How many years experience do you have in skill X?" in interviews, I don't know how to respond it correctly.
Because the culture difference, I am a humble man and don't sell me well. For example, I used a skill X on and off for the last 5 years. When I was asked, my answer was try to calculate the sum of pure months of using the skills. So I always don't get opportunities.
So what is the correct answer?
in 2012, I had used xxx for 4 months. in 2013, I had used xxx for 1 month. in 2014, I had used xxx for 5 months. in 2015, I had used xxx for 6 months. in 2016, I had used xxx for 5 months. in 2017, I had used xxx for 11 months.
Can I claim 5 years experience?
