I have an interview and the interviewer's name is Erjie. I'd like to be able to pronounce when I get there. Can anyone give me guidance on how to pronounce his name?
FWIW, the person is from Singapore.
I'm assuming that this person's name is spelt according to standard Mandarin Pinyin.
[jie] is pronounced something like "jyeh".
A fair approximation of the close-mid back unrounded vowel is IPA /o/, which is the vowel in the English word "go".
The retroflex approximant can be given as the consonant in the English word "red". See http://www.lel.ed.ac.uk/research/gsound/Eng/Database/Phonetics/Englishes/ByWord/Word_075_red.htm and listen to "Standard American".
Putting this together, and ignoring the tones, you should be pronouncing the name like the following:
