I wouldn&#x27;t say &quot;big&quot; tech company so much as &quot;name&quot; tech company.  Lots of big tech companies exist (e.g. HP, EMC, IBM, GE) that generally don&#x27;t carry any kind of magic imprimatur.<p>I think the previous response is correct in that there is definitely a halo effect that makes one seem more credible. Example was an article I was just reading entitled something like &quot;Ex-Googler Gives Life Lessons&quot; and it turned out the person was 25.
