Today I was questioned at the immigration upon arriving to Singapore, there were few times where I stayed for nearly a month here. But not the last few times, still, I got questioned what am I doing here and I did not know what to reply
My questions are :
1. What should I answer next time whenever asked what am I doing in Singapore? I stayed for at least 2 weeks everytime and I am actually looking for a job.
My S pass got rejected once and I appealed, which still in process and might take at least 1 more week.
2.Now that I am only allowed for 1 week in Singapore this trip, will the next trip be difficult ? Or even deported ? How to avoid this situation ? I really want to work here, I studied here for my degree.
EDIT : Also, I Have a very different stamp / chop, this is the first time I've got this kind of stamp from Singapore
Can Anyone tell me what does it mean / indicate ?

Thank you very much for the replies, I appreciate it
