I think that overall interpersonal skills are just as valuable as technical skills. I do not think that anyone is capable of doing everything on their own. By default this means that everyone needs help at one point or the other, and this is especially true in the workforce. Without interpersonal skills it is harder to network and be able to have more resources to complete a job. Additionally, we live in a world with 7 billion people on it. The probability of there being someone with your same level, or perhaps better level of technical skills is quite high. Therefore, developing your interpersonal skills and making sure these are outstanding is crucial. However, without a certain level of technical skills there is no chance of getting the interview, job, recommendation, etc. This is why I believe that at the end of the day there has to be a symbiotic relationship between technical and interpersonal skills.
