This article is critiquing the unstructured get-to-know you interview. It is not critiquing highly structured interviews with clear goals, nor technical challenges, nor references checks or past performance.
In your example, how would you structure a series of questions and procedures to limit the risk of marrying someone who will abandon you or cheat on you? I think you can apply good interview process techniques to this quite well!
1. Have they been divorced or cheated on someone before? People who have been divorced before are much more likely to divorce again. The 50% divorce rate in the US is slightly misleading, as many of the divorces are concentrated in repeat divorcees. In fact, among younger (early to mid twenties) first-time marriages, the divorce rate plummets to something like 15-20%.
2. Have their parents been divorced or cheated? Children of divorced parents are much more likely to get divorced themselves.
3. Have they been physically, emotionally, or sexually abused as a child? People with traumatic early childhood experiences are much more likely to develop trust issues with long-term partners, especially if they never had extensive counseling.
4. Do they have a good relationship with their family? People who have a difficult or unstable relationship with multiple family members are more likely to see tumultuous relationships as a norm.
This is all equivalent to reference checks in a job.
Then a long dating / engagement period is necessary. How do you they treat you during this period? Do they cheat? Are they abusive? Do they leave you during a period of difficulty? Do you have the same religious views? Do you split housework evenly? Do you both want kids? How do you view money? The three most common reasons for a fight among couples are 1) money, 2) housework, 3) free time (and how to spend it).
People who are otherwise happy and well-adjusted adults who get married and then divorce bitterly after 10 years are not the norm. Most divorces can be predicted. And most divorces happen before 2 years of marriage. If you are aware of the warning signs and are not blinded by a "gut instinct" I think you can definitely minimize the potential for marrying a snake -in-the-grass.
