If it was a part time job, you may not mention it in your resume, but you should definitely talk about it in your SOP. Any experience that you have gained , any skills you have learned will add to your profile.
I hope it helped.
Thanks alot. But I had worked full time as I had some financial problems that time . So can I add it to my CV ? Will this 1 year + 5 months be counted in my work experience ?
