They will call or email for the interview invitation. If you've made it the first round of interview, you will be called back for the second round which they will then determine if your suitability for the role. The interview process was a pleasant one as the interviewers were nice and were genuinely curious (or seemed to be) at what you do and who you are as a person. Do take note that they are slow in processing applicants, as was informed by them. It'll take 6 weeks at least to be notified of your application status. I sent them an email inquiring about my application status, however, they didn't even bother to reply.
