Sercomm Embedded Software Engineer interview questions

Got an email after I applied. Asked me to review and take a written coding exam lmao (IN WHICH I DIDNT AHAHHA). They prefer people who are knowledgeable in c++/c pero okay rin with whatever language u know. It was medium-hard exam but heck it was my first time applying and attending interview as fresh grad and I forgot to code. They asked me to retake the exam because I graduated from the Big 4. (YES they prefer ppl from the big 4 pero still give opportunity to others naman). I didn't comeback because I took a diff path na. TOTGA ko somehow. I wished I aced it :<
