Questions about applying

They see your structured profile as it stands at the moment you apply, plus your CV if you have one attached. That snapshot is frozen - if you edit your profile next week, this application still shows what you sent today. Your salary expectation is never sent unless you choose to include it.
Yes. The match figure is for you, not for them - Koins Microfinance Bank does not see it. The apply button works the same regardless of your match percentage.
Because boards rewrite titles when they republish. All copies of this vacancy are the same job at the same employer with the same closing date. We show the employer's own wording and list the rest above so you know you have already seen it.
It appears in your application tracker straight away. Because this application is handled here rather than on an external site, you will see the status change as Koins Microfinance Bank moves it - viewed, shortlisted, interviewing or declined. Roles that redirect to an employer's own site cannot be tracked that way, and we say so on those listings.
This employer has not yet been checked against the corporate register. Regardless of any of that, no employer on this platform may ask you for money at any stage. If this one does, report it and tell us what they asked for.
