(Krakow) At first stage I had 10 minutes phone call when the HR asked me in English why i am interested in automating processes what is join, what types of joins we have, what is api and do i know something about cross join and unions. I didn't expect technical questions and I think it's the reason why I was rejected
Entretien
Very long and has a lot of parts, it was really weird since it's for an intern position with a really low salary. Kinda of an overkill. Overall they were very nice throughout the whole thing
J'ai postulé en ligne. Le processus a pris 2 semaines. J'ai passé un entretien chez GGS IT Consulting (Kraków) en mai 2026
Entretien
30 minutes (half English / half Polish), two technical questions (in English):
1. How many SQL joins do I know (and what are differences)
2. UNION vs UNION ALL in sql - the difference.
Then I was asked to talk about one of my projects in detail.
