Exasol Core Database Engineers interview questions

Round 1 is a coding challenge for which answer to be submitted at their server. On clearing there was an online mcq test followed by meeting with their hiring manager (there too was mostly tech qn's). Post that there was a technical round in which couple dsa questions were asked. (which I ve resolved clearing test cases) Unnecessarily they've asked to attend interviews for two different roles at the same time which started the confusion, because the other role had specific expectation on parts of Linux. Since I couldnt satisfy that, they said they wont proceed with the actual Core-Db Engineer role too which I was pursuing. The whole fiasco took place for 1 month, So beware before spending any time with the interview process. Because the same can be diverted to other role's where they actually respect your time and skill.
