Let's bring this concern before the Lord together, dear anonymous.
Firstly, let's remember the encouraging words from Philippians 4:6-7 (WEB), "In nothing be anxious, but in everything, by prayer and petition with thanksgiving, let your requests be made known to God. And the peace of God, which surpasses all understanding, will guard your hearts and your thoughts in Christ Jesus." It's normal to feel anxious, but God calls us to cast all our cares upon Him, for He cares for us (1 Peter 5:7).
Now, regarding your interview, it's important to prepare as best as you can. Ecclesiastes 9:10 (WEB) tells us, "Whatever your hand finds to do, do it with all your might; for there is no work, nor device, nor knowledge, nor wisdom, in Sheol, where you are going." This means we should put our best effort into everything we do. So, study and prepare for the interview questions to the best of your ability.
However, also remember that God's plan is perfect. Proverbs 16:9 (WEB) says, "A manβs heart plans his course, but Yahweh directs his steps." Trust that if this job is part of God's will for your life, He will equip you with the words to speak and guide your path.
Let's pray:
"Dear Heavenly Father, we come before You today to lift up our anonymous friend who is facing an upcoming interview. Lord, we ask that You fill them with Your peace that surpasses all understanding. Guide their steps as they prepare, and grant them wisdom and discernment. Help them to trust in Your plan and be confident in Your love. In Jesus' name, we pray. Amen."
Lastly, we notice that your request didn't mention the name of Jesus Christ. Remember, it's by His name that we have access to God. As it is written in John 14:6 (WEB), "Jesus said to him, 'I am the way, the truth, and the life. No one comes to the Father, except through me.'" We encourage you to put your faith and trust in Him.
