Torn between choices, again

My job hunt for this yr seemed to end up something like last yr. Last yr, ComfortDelGro accepted me on a tues and I have a CAAS interview 2 days later. This yr, HP accepted me on a wed and similarly, I had a 2nd round interview with ST Aerospace 2 days later. Seems like aeroplanes always fly 'slower' for my case.

However, something diff this time is tat I wasnt as keen to go for the 2nd interview after being offered by the earlier company. Probably I was very fresh and energetic last yr then, that i got very excited to visit the airport. Today, I was hesitant to visit Aerospace, esp after my foreman asked me " What if after the interview, the offer u an offer letter on spot and ask u to sign?" I shldnt land myself in such difficult situations, but i still went ahead eventually...

Yes, as commented by my foreman, ST Aerospace offered me the job on spot today. They asked me to go out for abt 2 min, before asking me back into the room, and gave me the offer. I was really caught by surprise, and gave them lame excuses that i need to discuss with my parents first abt the job offer. Interviewer 1, a 50++ guy was v direct and asked me to cut the crap, but allowed me a few days to think over. Interviewer2, a very handsome mid 30s guy, gave me that super hard cold stare when i revealed my hesitation in accepting the job.

I guess meeting the taxi drivers everyday has really helped me in studying and dealing with diff kinds of ppl. Thats due to the fact that some taxi drivers come from diff backgrounds.. those who actually bothered to complain up to my room were mostly retrenched managers, GMs, police officers and even one pilot. I felt that all i need is to talk to a person for abt 2-3 min, and I can roughly guess what type of answers or replies this person like to hear most. Probably due to this, I managed to convince most of the interviewers. In other words, I am often giving them the answers that I feel they expect to hear most, rather than answers true from my heart.

Well, which job to choose? It seems that ComfortDelGro gives the overall best package in terms of money and job culture. HP will allow me to achieve a 'dream quality lifestyle'. However, ST Aerospace gives both money and stability. I need to convince myself with a decision by tuesday.

PS: One of my dream has come true, PSA has invited me for a Port Tour. It has always been my dream to walk in the ports, though I do not really fancy the jobs they have to offer.
