Spot.io Software Developer interview questions

I got an explantion about the job, asked about my previous positions, then three algorithmic questions, first two were very easy, third question was more tricky, and the interviewer did not seem to care much for the thought process.

its was very convenient,nice hospitality, new offices in tlv, good atmosphere,you should try and get it. the home ex was intensive but a productive one, so you get an idea what the company does. dasdasdasddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddd
