Recruitment job in a Consultancy firm does offer you experience to interact with HR departments of your clients, but is no substitute to a HR generalist role in corporate HR. For what reason you had quit from the corporate HR environment is best known to you, but I won't call it as a thoughtful gesture.
Never mind, now focus on your current job, learn all aspects of recruitment for a couple of years, establish contacts & plan switching back to the corporate sector.
Any job, in my opinion, can contribute to your profile for career growth in the HR domain provided you have taken it seriously. It may be wrong to say that experience in an HR Consultancy firm will not be useful in the long run. You must learn what 'Talent Search' means in totality & how a recruitment consultancy firm adds value to this process. If your clients are able to get through your consultancy the type of people they need, you would have acquired some competency in this area. Therefore, be focused on your job & avoid restlessness caused by this state of confusion.
Remember, Talent Search is the start point of Talent Management. And today you are a part of that Talent Search process , not for one but multiple organizations. Good luck & do well!
