Here is a short prayer that you can use before a job interview:
Dear God,
As I prepare for this job interview, I ask for your guidance and wisdom. Please give me the confidence and clarity of mind that I need to present myself well and to answer the questions that I will be asked.
I pray that you would open up doors of opportunity for me and that you would lead me to the job that you have for me. Please give me the strength and courage to trust in your plan for my life, and to know that you are with me every step of the way.
I pray for your favor to be upon me during this interview process and for your hand of protection to be over me.
In your holy name I pray, Amen.
