As the years go by, I keep on hearing more and more stories of people who I know first hand -- who went out prior and rejected or got rejected -- and then years later - they ended up revisiting it and ended up getting married. One instance, they first met 10 years prior. Now, there are so many singles that are already in the late 30s, and in their 40s - and it's sad shadchanim have to call up and tell the boy -- the girl has frozen her eggs.
I can't imagine that it's hashem's will that people get married so late -- but if there are so many older singles - it must be that people are rejecting their basherts.
Another problem is that dating process itself isn't natural -- one a date, one is being tested by the other person -- and when one is tested - one is not natural and one is not oneself.
And I think that applies as well to job interviews -- There are people who are never able to make a good impression on a job interview - but those people might be the absolute perfect fit for the job.
