i know, it was so hard finding my very first job at 16. i gave out so many resumes at at so many different areas! my first job ended up being through a connection.
oh, i only got one interview when i went job hunting at 16. it was for mcd's and i got rejected. lulz. i'm not surprised they rejected me.
they asked me if i was only available for the hours i put down (which was like, 4pm-7pm) and i said 'yeah, i have to catch the bus and it only comes like, every 4 hours'. lol. and they asked me if i played any sports after school (y'know how they ask that to see if i'd be tied up over the weekend) and i missed the point of the question and started listing every sport i ever played. and they asked me what my favourite burger was, and i was like, 'huh'. when they asked me why i chose mcd's over KFC i said 'my friend works here and said it's really good'. they asked for my friend's name, i told them, and turns out they don't like her. yeah, put zero preparation into this interview.
anyway, after i quit the job i got through a friend (had to go through an interview for this though and did well. i learnt from mcd's), i ended up getting a call from one of the applications i put through ages ago.
so yeah, persevere. lol.
