Does the Istikhara prayer in this case indicate not completing the field of programming, and what are the indications of the Istikhara prayer for the necessity of an action or its absence, and is it for seeking Allah's help, and does it have specific supplications and times?

The Istikhara prayer means a servant's request to his Lord to choose what is best for him in what he intends to do. Its manner: praying two rak'ahs other than the obligatory prayer, then supplicating with the narrated supplication while naming the need in its place. Istikhara is legislated for all matters, whether great or trivial, and it is performed for recommended and permissible matters, not for obligatory or forbidden ones. After Istikhara, the Muslim proceeds with what he has resolved, regardless of whether he feels at ease. It can be prayed at any time except during the prohibited times, unless there is a fear of missing the matter.
