What would you say your strengths are?
In coding test, one question was to find the count of unique characters in the given string. Other question was to get the country code of the given country from the given URI where you can pass country name name & get some data. Then you will need to parse that data to fetch the country code field data. The manager was looking for some 10+ years experienced person who designed & built the enterprise level applications from scratch, means some person who can confidently fake his/her intelligence & can fit to DBS policies to fool the people. He wanted to know that design. In short, its all fake show-off here that they do exceptional work but reality will be total opposite.
