Arrived early and did a 30min Problem sum test..perhaps test your IQ..interview was scheduled at 11am, waited till 11.15am and called HR as have another appointment at 2pm. The hiring manager did not come and another senior came instead. Was told the hiring manager was held up by the President for some reasons..well..we candidates also made our efforts all the way to tampines industrial area..2nd such similar case occur with semiconductor interviews..we candidates also deserved to be respected and our time are precious too, even though now is employer's market!
