That is obviously true in some sense. Look, I worked in Petronas before for 10 years and have established a lot of network. Most of my good friends are now the GMs and some SGMs of big Department/Divisions in Petronas. So when my brothers (2 of them) were interested to join the company, it's a no brainer that I used my network to get their feet in. They still have to go thorugh all the interviews (I know one of them had to go to 3 interviews as well because he had 6 years experience prior to joining Petronas).

One of the reason why I keep stressing the importance of networking. It helps to expedite matters, but if your brothers/sisters are not qualified, they still won't get in.
