FIS interview questions

Went through two stages, gave them everything they needed and more and was told they’d be in touch in the next few days with next steps. Since then got completely ghosted despite chasing multiple times. Horrendous experience and extremely silly of them as FS is a small world. Heinous company

It is easy when you're good at c, c++, any query language, Linux os. First i fell difficult they cover all of these topic from beginner level to advance level. and then 2nd round is manager round in this round they asked me about my past experience from previous company and cover logical question. 3rd is HR round.
