DS - 160 End date for Previous Employer

[MekaP]

Hi,

I have H1 visa valid till Sep 2022 for Company A and I got my H1 transferred to Company B and visa approved From Jan 2022. I worked for both Companies A and B from Jan 2022 to July 2022. Now I would like to resign from Company A in July and planning to visit India. I also planning to go for Stamping on Company B. Here is my question
1. When filling DS-160, what end date should I mention for Company A and what would be the start date for Company B.

Please let me know.

Thanks
