  WASP-33 is one of the few $\delta$ Sct stars with a known planetary
companion. By analyzing the stellar oscillations, we search for possible
star-planet interactions in the pattern of the pulsation. We made use of the
Transit and Light Curve Modeller (TLCM) to solve the light curve from the
Transiting Exoplanet Survey Satellite (TESS). We include gravity darkening into
our analysis. The stellar oscillation pattern of WASP-33 clearly shows signs of
several tidally perturbed modes. We find that there are peaks in the frequency
spectrum that are at or near the $3$rd, $12$th and $25$th orbital harmonics
($f_{orb} \sim 0.82$ d$^{-1}$). Also, there is a prominent overabundance of
pulsational frequencies rightwards of the orbital harmonics, being
characteristic of a tidally perturbed stellar pulsation, which is an outcome of
star-planet interactions in the misaligned system. There are peaks in both the
$\delta$ Sct and $\gamma$ Dor ranges of the Fourier spectrum, implying that
WASP-33 is a $\gamma$ Dor -- $\delta$ Sct hybrid pulsator. The transit light
curves are best fitted by a gravity darkened stellar model, and the planet
parameters are consistent with earlier determinations.
