Applying to KLLM - need some info first

Trying to choose the right trucking company is tough enough as it is and now they've added more stress to it with the potential of a hair follicle test. had a death of someone close to me 3 weeks ago, too un-prescribed sedative to get some much needed rest. Now i am considering apply to kllm. i came to this forum hoping & praying to get the answers to two question:

Does KLLM do hair follicle testing? The information you provide me must be correct otherwise my driving career could pay the price.
Can anyone share their knowledge and experience of driving for them?

Please help
